Atom Pack 18L

February 1, 2021

Excellent backpack!

Just enough for everything you need for the day. Comfortable, great materials, very strong and zippers are awesome. My favorite backpack

Perfect everyday pack.

Nearly perfect design Only wish it had a side mesh bottle holder.

Little pack, but big enough for my needs!

Love the pack- I use it for small hikes; a sweater, some food, etc. It fits on my body perfectly and is comfortable. My ONLY quibble is that I don't like brand names on the outside of what I wear.

Fits everything I need

I carry this bag daily for work. Typically I carry my wallet, keys, a change of gym clothes (minus shoes,) a few small notebooks, 2 organizer bags, a snack, & an 18 oz Hydroflask. It has kept me from overpacking for a 12-14 hour work day. It has saved my neck & shoulders from carrying a purse thats way too heavy.

Perfect everyday bag

I can't say enough good things about this bag! I've been using it daily for just over a year and I love it. It has held up beautifully to all sorts of different uses like work, road trips, international travel, weekend trips and school and it still looks brand new. The features are very straight forward which prevents me from accruing clu... Read Moretter and keeps my items quickly at hand. The two internal organizing pockets are surprisingly capable of holding plenty of gear (i.e battery bank, phone cord, screen cloth, headphones, cash, eye drops, mini multi tool, chap stick, gum, Purell and a travel cologne) all without bulging. the main compartment zips all the way open which was a very thoughtful design for a compact bag. I can typically fit a reusable water bottle (24oz), a couple of books, notepads, pencil bag and a jacket without having to stuff to zip. The laptop compartment is a huge plus. it's way more padded than a typical laptop sleeve and its fairly concealed unless you know that its there which is great for tucking away important things like a passport when security is a factor. The outside stash pocket is a nice bonus feature. I tend not to keep too much in there because it can get bulky pretty quick but its excellent for a snack bar and some hand wipes. Overall I absolutely love the Atom pack. One of those items where you get more than you pay for. It fits comfortably enough to wear all day if you have to and it truly is a minimalist work horse.

Perfect pack!

Its small but great for the airport, work, the mountain... anything! My fav pack now!

Professional Use

I love this pack for work and I use it instead of a combined purse and tote bag. I am small and I like the narrowness of the fit on my back. I can get my 12” Ipad Pro with its protector case into the laptop sleeve. I can also use the outside pocket for a water bottle, which was not clear from other reviews. The black pack is a wonderful light grey ... Read Moreon the inside which is not what I was told on the chat when I asked the interior color. When I was told that it was black inside, I almost did not order it. However my friend who is familiar with Patagonia packs said that their packs always have a light color inside, so I went ahead and ordered. Yay. Another great feature is that you can completely unzip the main compartment. I find this pack very versatile. I use light weight travel organizer bags inside the pack for the various things I need during the day or night, and so I like the simple interior design and do not miss a bunch of organizer pockets. I can use this in casual to dressy casual settings and the overall look can fit into a professional setting where my black Atom pack does not seem to be noticed at all.

Perfect bag for work travel

I purchased this bag for a cross-country work trip. I love everything about this bag including it's compact size. My 13" laptop fits perfectly and I had enough room for all the essentials. The only negative for me with this bag is the lack of a water bottle holder. I love the color and fit of this bag. I highly recommend it.

November 22, 2019

Perfect for what I needed it for!

I love this backpack! Its a perfect size for almost anything but long trips and its user friendly. I wish it was more water resistant/proof but besides for that, its a great pack.

October 24, 2019

Daily bag

Wanted this to be able to bring my computer conveniently in a daily bag. Just enough room for my MacBook, charging cords and other essentials--big enough for a few file folders too.

October 23, 2019

Awesome bag

The bag is perfect to fit my laptop, notebook, and my folders in for class along with everything else I need. I am happy with the bag.

October 16, 2019

Exactly what I needed

Atom Pack 18L is exactly what I needed. During the work week also when I go to trips I will carry it instead of a purse. It is a great size and thoughtfully designed compartments. I highly recommend it.

Small, Smart Design with Chest Strap

This bag is awesome - I recommend it to all minimalists. Very small and will make you question what you really need. The laptop side sleeve gives easy access to laptop without having to open the main compartment. And if you want to repurpose for a weekend hike, you could put a hydration pouch in the sleeve.

Wear and Tear

I recently bought this pack and although it has a nice and slim design, the stitching near my laptop zipper started to become undone after about a week. It is a nice design and can hold quite a lot of items but gets roughed up pretty easily. I had to send it in for a repair which will take a long time to get completed. I should've just asked f...

Hi Curtis! We're sorry to hear that the stitching started coming out so soon. We wanted to thank you for keeping it out of a landfill, and getting more life out of it.

Working as well as one would expect!

Patagonia (or Pats-Gucci as it is often called in my part of the PNW) is know for durability and quality. My new pack doesn’t disappoint!

I recommend this pack for what it’s made for.... small, quick trips.

Just right for extra pocket.

Just right for extra pocket. Phone , wallet, camera.

Love this backpack

Perfect size, my laptop was about 1/2 inch too big to fit in the zipped part but it fits perfectly in the big part. My only suggestion would be to add a water bottle holder on the side.

Great daypack

This backpack was the perfect size I was looking for. I had bought a cheap sling pack last fall and it was big enough for my tablet and other items but I couldn't shove a jacket in there on days when I might need one.

Really great lightweight bag that's perfect for small essentials. Love the color and the multiple pockets

Tiny..... Not useful

I should have looked more closely at the dimensions, this backpack is basically toddler sized.

Great Pack!

Love this backpack, especially the side zip pocket for my laptop. I use it for everyday commuting. I wanted something small but capable for my commute to and from work on the crowded train and this hit the spot!

Perfect for work or travel

I bought this to keep my wallet, phone, planner, notebook, chrome book, pens, and books—in short, all I need to do my work—in one safe, small, convenient space with a great warranty. The interior pockets hold the phone and wallet for easy access; the front compartment is a great place for a shell or a collapsible umbrella. Excellent on a plane. I’d...

Near-perfect backpack

This bag is the exact right size. It's light and small enough that you won't get bogged down if you're only carrying a water bottle and a wallet. But it's big and robust enough to carry your 13" laptop, iPad, liter nalgene, sweatshirt, rain jacket, and files. For carrying files, I recommend a semi-hard plastic file folder t...

Great pack but hurts my shoulders

This is a great bag, I love it for my daily commute and it's the perfect size. However it seems like no matter how little I store in it, my shoulders get so sore I can't wear the bag for more than half an hour. I've used Patagonia packs before and never had this issue so this is a huge flaw for me. Not sure what it is about the shape...

Smaller than it looks

I didn't have a good reference for what 18L would be, but based on the pictures I expected it to be bigger.

Nice pack, great size, but one flaw

Have taken this pack on a lot of planes/trips. The padded laptop/electronics pocket is great, internal organizers are nice; the one flaw, and what would be a great addition, is a water bottle sleeve.

Personal Item Size

I originally bought this because it fits a criteria for a personal item (under seat bag) on an airplane and also a small day bag. I was able to put my jacket and my companion’s leather jacket in it when it was warm in San Francisco.

Fantastic pack

After a neck injury I could no longer carry a purse with all of the things I needed to carry for work. I didn’t want a larger backpack because I would over pack if I did. I can carry my tablet, life essentials, and a change of clothes if I’m on the road. I’m buying another couple for my husband & brothers.

Perfect for city trekking

This pack has comfortable padded straps though I suggest that the straps do not sit on bare skin as they rub slightly. Other than that ,this is my favorite bag.

Streamlined and durable, but ruins clothes

Like a few other models, the straps on this ruined a hoody of mine to the point where it's all "balled up" near wear the mesh hits my back and shoulders. A shame, since it's a nice pack.

College packpacl

Was looking for an ethically made backpack to get me through college. This pack carries my school supplies, breakfast, and laptop with some room to spare. Also, the laptop compartment can fit my 14 inch laptop with just a little extra wiggling

Please bring back the Poco Mucho 20L. It was the perfect backpack! This Atom pack, as well as a couple others, were recommended to me by one of your agents as the closest similar but they are really nothing alike. I'm looking for a pack for my rising pre-K child to use this year and for the first couple years of elementary school. We've h... Read Moread a Poco Mucho 20L and it is the perfect size for a child's back... plus it had all of the right features... external water bottle compartments, enough room for a lunch box to fit inside, room for a book and a little school work to come home, and a WHISTLE built into the chest buckle. Before our other Poco Mucho became my oldest child's school backpack, it was our diaper bag/day bag. My hands could hold onto two little boys and I always felt safe knowing I had a whistle at the ready. Now, I feel safe knowing my oldest has a whistle if needed and I don't have to deal with cheesy cartoon characters or an oversized backpack not designed well for a child's body. Please, please consider bringing back this bag or incorporating some of its great qualities into another of your packs approx. 20L packs!

Low profile good for air travel, around town edc

This Atom Pack 18L (1098 cubic inches) day pack is very handy. It first caught my eye on the sporting goods store rack because it is all black (no bright trim, no gray rear panel, just all black) and in low sheen, but smooth surface, nylon. I like nylon better than polyester (which most packs are made from, because it is cheaper) because it withsta... Read Morends abrasion better and has greater tear strength with thinner fabrics. I like smooth surface nylon better than "sanded," fake-canvas nylon because it doesn't act as a magnet for cat and dog fur the way sanded Cordura fabrics do. The threads are thick enough to give the surface some texture, but not the ginormous threads used in ballistics-style fabrics were you can really see the huge weave. So, this looks more robust than ultra-light fabrics, but not overbuilt like ballistics fabrics. It may sound like I'm nitpicking, but these designer choices are why the fabric has a good "hand" and looks good. In contrast, there is a manufacturer of "security feature" packs and bags that also uses smooth surface nylon, but their threads are smaller and tighter with a resulting totally different look and feel. The fabric Paty has spec'd here looks robust and modern, not like the cheap nylon and polyester "flight bags" from the 80's. // This pack fits narrow on the back, and is low profile (narrow depth from your back to the front of the pack) so you won't whack fellow passengers when you are disembarking and the aisles are jammed and you can barely turn around. It won't stay low-profile if you jam a fleece to the bottom, but if you fold the fleece to optimally fit out to the bag corners, you'll be good to go. // Unlike many daypacks, this is more rectangular, since it was designed to hold a rectangular, 13" laptop. I confirmed that a 13.3" thin or fat (Thinkpad) laptop will fit, even though Paty only claims 13". A nice feature of the laptop slot is that it is "external" to the main compartment - between the main compartment and the padded back panel. BTW, that padded back panel is really thick, the one area that I think is a little overkill (but may not be, if you stow an iced water bladder here instead). It isn't suspended from the bag bottom, but it IS equally well-padded on the bag's bottom and far edge and along the top edge - the only unpadded edge is the zipper edge. That's 3 out of 4 sides well protected, which is awfully good. The compartment side panel is felt-fuzzy lined, and won't scratch a 12.9" tablet screen, but I think it would be insane to put a tablet that expensive with glass facing towards the main compartment without a screen cover. The foam pad on compartment-side is much less thick than on the back panel. You'd probably be ok if the main compartment just holds a fleece, but anything pokey or hard would me me nervous. // There's no external water bottle slot, which I think is appropriate for this slim and fast design. I like mesh bottle slots both for water bottles and for gloves, neck gaiter, bandana, energy bars, watch cap, you name it. The problem is, most water bottles have slick sides and will slide out of almost every water bottle slot, since the elastic used at the mouth is never enough to retain them. So my personal water carry preference is a Platy "film" bottle in the main compartment inside a zip mouth plastic bag in case of spills. // If you are doing longer hikes away from easy access to water, the laptop slot doubles as water bladder slot. There is an exit porthole at the bag's top; there isn't an internal compartment hook to hold a water bladder in place. // The shoulder straps show a lot of thought and quality. They are straight off a much larger pack, thick foam, recurved, breathable mesh on body side (the back panel is similar breathable mesh). There is a sternum strap, and thankfully no waist strap to dangle, catch on stuff, and generally annoy. I always vote for a sternum strap over a waist strap. I almost always need a sternum strap to keep the straps from sliding back over my shoulders. It's also a theft deterrent. And it can be snapped over an adjoining chair handle to deter grab 'n' runs. This one is removable is you don't like them. There are loops on the front of each strap where you can clip or carabiner something to the front. // The top grab handle is better than most but far from perfect. It is wide and thick enough to not fold over and bite my hand. It is more than just a loop to hold the pack on a sales rack. On the other hand, I wish Paty had attached the ends further apart on the backpack strap mounting area - the opening for my grip isn't as wide as I would like. Thankfully there isn't any plastic or metal tubing on this strap, stuff I hate. Just simple but thicker-than-most-webbing fabric grab handle. // There are two compartments. The first is "outside" on the front panel, a straight vertical zipper that opens up a compartment where you can fold a thin shell. You can also use it for travel papers, but I wouldn't put anything that I couldn't afford to lose here, since pilferage is easy by pulling the one-way sipper, with long fabric pull, down from the top. (The laptop slot is similar design but it's hard to pull out a laptop, easy to pull out a wallet.) // Still, I like the outside quick access pocket. I could see putting a flattish i.v. style water pouch in there, along with a Houdini or similar windbreaker. // The inside compartment is mainly BYOO - bring your own organization - except for an open top flat mesh pocket and a small closed fabric, zipper top flat pocket. The open-top mesh pouch easily holds my 6" phone, even in its drop in case. The zipper pouch easily holds my passport. There are two negatives: there are not drop-in pen slots, and the key-leash clip is inside the open top mesh pocket. I would rather see the key leash clip at the side or top of this panel, not inside the top mesh pocket, since I don't want my keys and phone inside the same pocket. // Other than the two pockets, there are no neat "tricks" in the main compartment - no mesh lined sunglass slot, no pockets for energy bars. // I think in the past Paty has engaged in "office/shool organizer panel overkill," but on this pack they maybe embraced their inner minimalism too much. Please move the key leash out of the phone slot, give us a couple of pen slots, and install some tiny "o" rings at top and sides so we can clip organizer pouches to them, without them simply slipping to the bottom of the pack - we need some accessory pouch attachment points. // All in all, this is one of the best designs I have seen from Paty in a long time. It's on the small side, but I plan on using it as my "personal item" at my seat, with my carry-on luggage stowed overhead. It's also small enough to use as an edc bag locally - a lot of my alternative bags are great in the airplane cabin, but oversized once I hit the ground. // The laptop/very large tablet slot is especially appealing. I seldom carry a laptop or tablet, but when I do, most of my bags don't work well with them. There isn't a well-padded slot to keep them from shifting around, and I don't like the laptop knocking around in the main compartment. This bag is small enough it won't get in the way on most days, but when I need a laptop for a cafe will accept it and protect it well. // In fact the laptop slot on the Atom Pack is so well designed and protective I don't think I will need a zipper sleeve as additional protection on my laptop. // I have to admit that when I saw this on the web page when it was released, I thought it was a joke - too small to carry anything meaningful, and too big for my minor edc stuff. But when I saw it in the store, it changed my mind!
