The Ultimate Carry On

This bag is amazing! I can fit the black hole packing cubes in one safe zippered and strapped space and all of my tech that I need access too in the padded access pocket. Perfect size carry on for any adventure!

Old model surface was much easier to wipe clean than the new one

An ideal gym bag and for shorter trips. I much prefer the older design.

Perfect Travel Companion

Only used this bag once for international travel. That said, I can't fault it. The design is well thought out and has enough space to accommodate my travel needs for a week-long trip.

Perfect Travel Bag

I’ve only done one international trip so I can’t comment on the ruggedness yet. The bag fits everything I need for 1-2 weeks of business travel. The electronics compartments are expecially well designed. The external styling is simplistic ans sleek.

November 9, 2023

Perfect size!

If you keep some flexibility (soft items / not overpacked) you can fit this under an airplane seat. If stuffed, it still fits overhead. Comfortable to carry and excellent design. I love this bag!

Well organized

This is great! Inside pockets are perfect. Needs some sort of pocket on the outside to access some things.

Perfect Pair for 2 weeks in Italy

I purchased both the 45L and 30L for a 2 week trip to Italy w/ just carry on luggage. 1st I received so many compliments on the Tinamou Tan color w/ red lettering. I was able to pack a suit, for dinner hiking pants and shorts, swim trunks, 3 pair of joggers, jeans, multiple long and short sleeved shirts, light weight fleece pullover in the 45L. The...

Great Bag, would recommend

Great update to a previous bag. Compartments are nice for organization and easy to use...and straps/suppport are an improvement to the previous version. Used for a two week trip abroad, as well as using for long weekends.

Excellent travel bag for quick trips via land / air

I love this bag! Great for airline carry to quick road trips.

Great for one bag travel

I have two previous versions of the MLC, I actually like the 2005-ish model I own best for its simplicity and durability, but this is a nice modern update for carrying a computer or small electronics along with your clothes and other item. In that way it is more versatile and that is how I travel these days. The old bag, I feel like you can jam mor... Read Moree clothes in, but then need a separate bag for my laptop, etc., so its a tradeoff. One thing to note, I am not a small guy at 6 foot 2 and 250lb, the shoulder strap that doubles as a waist belt it too short to wear as a waist belt and I will need to make alterations to be able to use. Also I received this new bag via the repair program for a MLC that had a nasty and undesirable seam tear but was at least 10 years old, so I cannot complain - that is outstanding customer service /retention. Thank you.

No small pockets - how could Patagonia miss this?

You're standing in the security line. Your pockets have the usual: phone, wallet, and keys. Time to take those out to go through the scanner. I don't know about y'all, but I take those things out of my pants and fairly easily place them in an easily accessible zippered pocket on my backpack I carry on. Every backpack has at least one... Read More.. It could be the crown pocket, zippered one at the top of the pack, pockets on the panel facing the outside, in the worst case water bottle pockets on the sides of the bag. MLC has none of those. None. Whoever argued to remove all small pockets thought it would be a great idea to have you open up the whole suitcase, dig into it, all in the security line, just to stash your phone, keys, wallet, maybe a boarding pass, earbuds - while you take off your shoes and hurry up because people behind you are waiting. And then you need to open that suitcase again to retrieve your paper boarding pass or your phone with the boarding QR code. Unbelievable. Small quick access compartments double for carrying charging cables for the phone and headphones at airports and on the plane. It is unfathomable to me how anyone would actually remove small quick access zippered pockets (virtually all backpacks have them) from a bag explicitly designed to be the all-in-one carry-on item, where they are most needed. Whoever thought of that is just a bad designer. No promotion, no raise. Meanwhile, my mind=blown.

Hey Connie, thanks for the review. Our apologies for the confusion, we think we may know what happened here. The hip belt on this bag can be pulled out and also doubles as the shoulder strap.

This is a very nice travel bag, but it should be noted that there appears to be an equal amount of Business/Document space compared to space for clothing.

Perfect for Travel

Bought this for a 2 month backpacking trip earlier this year, staying primarily in cities - it was everything I needed it to be.

Good but not good enough for this price

No simple external pocket makes this bag difficult to use. The external material on the front gets scratched by any simple contact, even in the aircraft cabin, and the appearance becomes terrible after a few months of use. I would add a photo here if I could. Otherwise it's a good bag with good space

I think this bag tries to be a bit of everything and doesn't do it well. I think they should have kept it as a solid backpack or a solid duffle. The problem comes from the waist/duffle strap, it's not long enough. The strap makes it a very awkward duffle and then you can't use it as a waist strap because it's too short. If you ...

Way too big!

I initially tried the smaller MLC Black Hole Convertible suitcase. I think it was a 30L or 35L size. I reviewed that one, but also included my own review including the bigger one.

Love the redesign!

I love the redesign of the MLC. I first had one about 20 years ago that was great, but not as burly or durable. My partner ended up using it for business trips. The new one is marvelous.

The compression straps help ratchet it all down and the shoulder straps and burly waist belt make it all comfortable to carry through the airport and around town.

Laptop pocket not true to size

This bag seemed promising so I would not need to carry two bags for trips or work. The problem is that it lists it can fit a 19" laptop, but my 17" laptop barely fits in either compartment. It sticks out of both compartments and I cannot close the zipper or secure the Velcro strap and my laptop moves around in the bag.

Great bag for international (or domestic) travel if you prefer to do so with only a carry-on. Plenty of room for travel clothes and necessities.

Read Morever, the 2023 MLC 45L is full of multiple lame compartments that completely cut into one's ability to pack lots of clothes. We did a side by side comparison with last year's model and found that the main compartment is more shallow and smaller overall than the previous version and that's the only place you really have to pack clothes. There is then a small area with two zipper pockets that you could pack some socks, underwear, maybe a t-shirt or two. The features continue to let me down as the lid is basically useless unless you carry a 20" laptop (no one carries laptops that big) and want to organize a drawer full of office supplies from your desk. If you're a business traveler looking for bag to carry all of your electronics, office supplies and an outfit or two then this is your bag.

Carryon for around the world

I bought the Black Hole MLC for my 2 Month travel around South East Asia. To put it simple this thing is awesome. It has the right size and Pockets to store everything you need and still counts a carryon for most airlines.The Durability seems also to be on point for what I have already been through with this backpack . The only let down is that som... Read Moree how i lost the hip belt / carrying strap it must have come loose on the airplane or on a Bus and I cannot find a replacement. Without the Hip belt the carrying experience is much worse since its not designed to be a full on bagpack. So if somehow dear Patagonia Team you could offer a replacement Belt that would be greatly appreciated so I can kept exploring the world with this awesome backpack.

Mini MLC

Really thought out piece of luggage. I was happy purchase one before they were sold out again. Fits under the seat or standing straight up in the overhead luggage area.

This bag is awesome. Lots of pockets for everything. Can store it under airline seat or overhead. Traveled all over with it. Great bag.

Versatile Travel Carry-On!

I bought this bag to use as a carry-on for domestic flights in the US. It worked perfectly on my Delta flight, though one of the two small gotchas I encountered was that because it's a soft case, it can expand beyond what will fit in the overhead compartments. Had to kind of push it a bit to get it to fit, but I mean I really had this thing pa... Read Morecked full! Only other thing is that because the waist strap doubles as the shoulder strap, it can't extend very low when you're using it as an over-the-shoulder bag. I had the strap extended as far as it could go and the bag rested about at my waist, even with the strap on the shoulder on the same side as the bag. This was not the most comfortable while traveling through the airport, but by no means a deal breaker. Otherwise, it fit an impressive amount of clothes and supplies for my four day trip, and had more than enough compartmentalization to keep my things separate! Would absolutely buy again!

Inefficient Use Of Space

I was excited for the MLC 45, and hoped to use it for extended work travel and travel with kids. Its a huge bag, but only a portion of can be used for clothes. The laptop flap is huge, and just wasted space. It is designed for a 19 inch laptop. I live with a software dev, and have still never seen a 19inch laptop. In addition to the laptop storag... Read Moree, there is a whole bulky flap with tech organization on one side and some packing options on the other. This flap plus the laptop flap take up 1/3 of the bag size, leaving a too-small open area to actually pack clothes. The bulky extra flap should not even exist, and tech organization pockets could be added to the laptop flap (which needs to be sized down to hold a max 17 inch laptop). As an aside, thanks for the compression straps.

Great international travel bag with some caveats

Recently returned from 2 wks in Taiwan. This bag was perfectly enough for myself and some of my 6yrs old belongings (this was the only bag I brought with me by the way. I pack light when traveling international because I move around different cities a lot). I liked that I can carry like a backpack or a sling bag (was very helpful during busy commut... Read Moree on the bus and train). There are some caveats though and might not apply to others. The problem I have with this bag is the weight limit when traveling to certain Asian countries or on certain Asian airlines where the weight limit for carry-on is 15lbs! To Taiwan I had to unloaded some weight at the ticket counter. At 5'4 this bag is huge on me! I wished they have a 35L version like the Cotopaxi Allpa 35L. I noticed Patagonia has the 30L version but I think it's small for me for international travel with only a backpack. I also wish they have a smaller outer compartment for a quick easy access to smaller items like a passport going through security. As much as I want to keep this bag, the 45L version is too big for me. Wishful for 35L version in the future. Going to settle on the Cotopaxi allpa 35L for my next international trip.

This bag has a lot of different configurations to carry it which is nice for traveling. It also has multiple partitions and storage areas that keep the contents from mixing together. It seems very well constructed.

Could this be the perfect carry on?

Bought this from an outfitter last min for a 10 day fly fishing trip to Cuba. This thing is incredible. well thought out. Lots of space, more than it looks like it can carry. Well thought out pocket placement. Didnt even need packing cubes as each segment holds specific items. Comfortable straps, looks good. Maybe an exterior pocket would be great ...

Comfortable & Organized

I purchased this bag ahead of a 3 week backpacking trip and it was everything I hoped it would be - organized, lightweight and versatile. It fit easily into the overhead bins on my flight and the two zippered pockets made it easy to grab things on the go. I'd recommend this to anyone looking to replace their carry on!

January 8, 2023

perfect for pushing the carry-on limit

Because I can carry this bag on my back, I've never been issued the dreaded pink gate checked bag tag. Yet it carries as much, if not more, than the ubiquitous black roller bag that always gets nabbed at the gate for less than prompt priority boarding passengers or unfortunate Zone 7 passengers.

January 4, 2023

All purpose and organized

This bag brings organization to the sloppiest commuter. Plenty of room for laptop and multiple chargers; clean and dirty clothes, + hidden features throughout. This bag is so adaptable for 1-4 day trips, seems durable - and great color combos make it easy on the eyes. This is my go-to bag for any short term traveling.

January 4, 2023

Spacious and practical

Simple and clever design; the bag separates business/office and apparel, while giving you options on how to move through the airport/train/ruck. Very smart details throughout - but missing a small exterior pocket for keys, sunglasses or snacks. Still a 5 star product - bulletproof and stylish.

January 3, 2023

Quiver of One!

This bag works perfectly as a travel carry on, overnighter, daily work/school shoulder bag, or even a smaller backpack. Super versatile for the size and compliments the rest of the Black Hole lineup.

Excellent design and function

Another excellent product from Patagonia. Bought this with with the immediate intention to replace my old laptop bag and then promptly used it on a week long trip to Costa Rica, the pocket and compartment layout was intuitive and easy to use, and the padded/zippered laptop compartment put me at ease when putting my computer in it. I get the feeling... Read More that this bag will be my new sidekick on adventures in work and travel, highly recommended!

Wish it had a hip belt.

Great pack but with the amount of stuff you can put in it, it should have a hip belt. I see the new version does, how about a retro fit for all of that bought one earlier.

Great travel bag

Just returned from a week in Europe and used this bag as my carry-on bag. It holds a ton, I had no trouble getting it in the overhead bin in the plane, and I love the organization built into the bag.

Good, Almost Great, Travel Pack

I've owned this pack for a couple years and have used it for one week trips as well as a four week European travel.

Patagonia Black Hole® MLC® Convertible Suitcase 45L

I really wanted to love this bag- it had pockets and a strap and could also be used as a backpack...but at it was just too big for my frame. I'm 5'2, and the backpack was gigantic on me. The design is amazing, and for sure, buy it if you are 5'5 or taller. If not, go for the 45L black hole duffel; it will fit your frame better!

Hi Randi! THank you for taking the time to write us a review. We're sorry to hear that the bag was too large for your frame. We greatly appreciate this feedback and we'll share it with our design team.

everything you need but small it enough to be easy

I have been traveling on planes with my black hole duffels for years but they always felt a little overqualified to sit on a plane. This is my dedicated weekend or eeklong tavel bag. Bigger than a backpack but smaller than a 90L duffel. And it's just like any other Patagonia product, you are amazed at the quality when you open it and then say ...

The Best Travel Bag!

This is a great bag for travel, whether by plane, train, or car. The bag is very thoughtfully designed and it is perfect as a carry-on when flying, but equally well suited for traveling more locally via train or car. I mainly use it as a backpack and look forward to getting the 26L version to use in tandem as a shoulder bag. I can easily fit a week... Read More's worth of clothes/gear in it. Before purchasing this I looked at Tom Bihn, Osprey, and many others. I think this bag has the best balance of versatility, functionality, and robust construction. I always steer clear of anything with wheels as I see them as a liability and limitation. This bag is perfect for adventures on or off the trodden path. I look forward to using it for many years to come.

Great Travel Bag

I am beyond pleased with this bag. Ive used it exclusively for travel and it has been perfect for my needs. The pockets and pouches are plentiful and make sense. I typically carry a 15 inch laptop, an iPad Pro, power banks, chargers, and my Nintendo Switch in the back compartment. The way the compartments open completely makes taking out my elect... Read Moreronics through security quick and easy. The front compartment has so much space as well. I put my travel pillow, extra clothes, and and extra electronics bag for easy access. The top pouch is perfect to get to my headphones quickly. It fits completely under a plane seat when placed perpendicular to you, but will stick out quite a bit when placed parallel to you. The shoulder strap doubling as the waist strap works exceptionally and is easy to convert as needed. Wearing it over the shoulder is comfortable. I typically carry about 9kg or almost 20lbs of stuff and configure it with the straps and waist belt. The weight is unnoticeable and fairly comfortable. The only thing is the chest strap just kind of seems to be an afterthought but it gets the straps tight nonetheless. Overall, I love this bag and am beyond happy with the quality and feel. I am looking forward to putting it to further use in the future.

Roomy travel bag that packs well

I recently used the MLC black hole convertible suitcase for a 3 week trip to Patagonia (yes, the irony is not lost on me). The bag was the perfect size for the 22 lb carry on weight limit. The internal compartments made it easy to pack all of our layers with extra pockets to organize our other essentials. When fully packed, the bag is quite large o... Read Moren my small frame, but the chest and waist straps help distribute the weight relatively comfortably. The straps to synch the pack down also help make the size more manageable. My one concern is the fabric. While most of the fabric seems very durable, I noticed that the wax-coated fabric on the back of the pack gets beat up quickly. After only a couple days of travel on buses I had multiple scratches that make the pack look old and used. I can't imagine how it will look once I have to check the bag through an airline. I stopped by a local Patagonia store to ask for recs to maintain the fabric, but they didn't know either. It would also be nice to have an easily accessible smaller, external pocket that could fit a wallet, phone, passport, and some food on the go as well as a water bottle holder in the future.

Best "suitcase" out there

This is the perfect bag for a quick trip. I use it mostly for work travel, but for other shorter personal trips as well. Its super easy to carry and great for organizing all of my stuff.

November 11, 2022


The layout and finish are brilliant. It holds more than you'd want to carry for very far, but also trims down for smaller loads. The only suggestions would be a water bottle holder, an outside quick access pocket or two, a pass-through phone charger, and a longer waist belt. It isn't big enough to fit around my 40" waist - but might ... Read Morebe if I alter the ends of the belting. Not inexpensive, but it feels substantial enough to last for many, many years. Love that it's made with recycled materials.

Excellent Carry on

This bag works really well as a carry-on that can be used as a travel backpack. The suspension system is pretty comfortable (for a square-shaped carry-on), and the waist band doubling as a shoulder strap works great. It has lots of sleeves and pockets inside, but they don't get in the way if you aren't using them.

October 26, 2022

This bag is pretty awesome!

This bag is pretty awesome! I just wish it had a little more padding behind the laptop sleeve. The carry options are great - back pack vs over the shoulder. The compartments work well.

October 18, 2022

Well made but not great for travel

Well made but not really designed to wear as a backpack thru airports, etc. I need a hip belt to take weight off my shoulders but the hip belt does not work well. I have the 45L and the smaller size may work better. Loads shift as well.

Great weekender bag

Great bag, lots of volume and compartments. The carrying options of shoulder strap, rucksack straps or handle add to the versatility of the bag. Only wish there was a small compartment on the outside of the bag for easy access to passports etc.

Amazing bag!

My wife gave me this bag as a birthday gift. I was looking to get the MLC 25 but she got confused and got me the MLC 45. At first, I thought it was going to be too big and it is if you plan to use it as an EDC, but I use it for travel and it works perfect. It is almost the size of a carry-on but it doesn't feel that way unless you fill it up... Read More to the brim. For the compartments, it is nice how you have your laptop in a separate way so going through the airport's TSA makes it a lot easy to just open the side of the bag that has the laptop and leave the rest packed. It does not have a tablet compartment, but you can still store your tablet in the zipper pocket behind the laptop and it works just fine. I have a M2 Macbook air and it has a tooooon of extra room left. I do like the material a lot, I've been looking to get the MLC bags for a while but the plastic feel of the previous bags stopped me from buying them but this bag has great material all around. The fit, is great, the handle passthrough is amazing, I almost never carry it through the airport. Having the option of stowing away the backpack straps and using the hipbelt as a should strap is genius! I do wish the strap was a little bit longer but at 5'10, it fits perfect for me. While I was reviewing the MLC25, I saw it has a water bottle pocket which the MLC 45 does not have, I wish it did as it is bigger so it has more space. Overall, very pleased with the bag, lots of room and organization in the inside and materials feel premium.

October 14, 2022

Great for packing

Doing two months backpacking through Europe and this feels like the perfect size. Big enough to hold everything I need but not too big.

So far I've only been using it for about two weeks but it seems to be a very reliable build. As long as it holds up I will be using this bag for a long time!

PERFECT travel bag

this bag is the perfect carry-on it's a great size and I love the organization compartments the backpack straps are super easy and accessible when you need them. After I bought this bag my partner loved it so much he ordered one for himself. Definitely a must have bag if you travel often.

Versatile, Roomy; Used for Travel, School/Work, Gym

I was looking for a 45 liter backpack with a hip belt that was not too heavy; the ability to convert to a sling and duffel is a welcomed bonus. The bag is crunchier and shinier (and more attractive in my opinion) in person compared to the photos; has a durable feel. There is very adequate organization without being too convoluted in such a way that... Read More it adds bulk or eats up the internal volume. It is comfortable to wear, and consolidating the hip belt and sling into one removable, convertible strap saves on weight and bulk. Built in compression straps can both compress the bag when carrying lighter loads and hold onto bulkier items externally (like a Jiu Jitsu gi, in my case). External loops can be used to attach items via straps or carabiners, etc.. The only criticisms I have are: upon receiving the bag, there were a couple small, loose threads on the inside, and I wish there was a smaller easy access pocket on the outside (but the flatter yet still cavernous tech organization section is easily accessible enough).
