Patagonia Men's Lone Mountain 3-in-1 Jacket

February 12, 2021

Great coat, large was too big

I usually wear large sized jackets and sweaters, but had to return this coat for a medium. I'm 5'11, 180lbs and the medium fits perfectly. In terms of warmth, I bought this as a casual 3 season jacket for coastal BC weather and it is perfect.

Great jacket!

Dont look any further this is the Jacket for you. I come from Sunny South Africa and have recently moved to the Northern hemisphere. This jacket has been my saving grace! Its warm and always keeps you dry. The even bigger plus is that you get 3 in 1 so i end up reaching for this jacket or a section of it year round! The build quality is like nothin... Read Moreg i have seen before and i look forward to many cold wet winter days with this jacket. Thank you Patagonia! Oh, one thing to note is that it runs a bit big (for me) normally i am a Large and i took a medium and it fits perfectly!.

Amazing jacket

The jacket is amazing. I wish there was a Kelp Forest (color for Tres 3 in 1 parka) version of this jacket.

A Hair Magnet

Love the coat, but if you have an animal that sheds, you'll be going crazy trying to get the hair off. We've used tape rollers, 3 kinds of brushes made for this, and our Dyson. Our upright vacuum cleaner with a hair removal attachment is the only thing that makes a dent in it. Patagonia, do you have ANY suggestions?

Hey there Ernest, thanks for your feedback on this jacket. This jacket is made of a more rough material that could potentially attract more animal hair than others. If you wanted to look at comparable jackets that would be less prone to this issue we would suggest the [Men's Topley Jacket]( or the [Men's Tres 3-in-1 Parka](

Exceptional warmth with a side of perfection

I have a few jackets from Patagonia and each purchase is better than the last. Not to say i appreciate my other jackets any less, just that this one is now my favorite. This jacket is great! I was looking for something that could withstand the rain with warmth and style. This checks all the boxes. While it may feel slightly large for someone of my ... Read Moreheight and weight I still feel as though it fits the way it needs to. A little about myself: 5’10” and 200lbs a little stocky. I always wear a large and with Patagonia the large is a good fit with some room to spare. Not too much since I don’t feel constricted while wearing this. The jacket itself separates becoming 2 deferent pieces. Inside piece: Full warmth puff jacket (with sleeves, not wool sleeves) The inside of this jacket is lined with wool equivalent to a vest. Outside piece: Full rain protection. Water will brush off. You can feel the quality. This alone can keep you warm in 40ish degrees while keeping you dry. Together this jacket makes an exceptional combo of staying dry and keeping warm in rainy or (Oregon) winter weather. 10/10

A good jacket, but not for my height

I tried this jacket after previously trying the Snowshot 3-in-1 in a Large. That jacket had decent sleeves for my height and sleeve length (6'3", 37.25" to the base of my thumb), but I returned it for other reasons. This jacket seemed like a great alternative, but unfortunately, it is not quite long enough for someone my size. I had... Read More to wear an XL to get sleeves that fit me adequately. At that size, the jacket was way too big for the rest of my body (I weigh 165 lbs, 36" chest). I was a bit frustrated since the sleeves fit me well on the Snowshot, but then I realized that ski/snowboard jackets usually run a little longer, so it all made sense. Unfortunately, this jacket did not work for me. I do not hold it against Patagonia, since I am a bit outside average dimensions for height, sleeve length, and weight. Ultimately, I've decided to pursue other brands that have Tall sizes. I'll continue to consider Patagonia for other products, though. If you are in the intended size range for this jacket, then it is very comfortable, warm, and sharp; and you'll enjoy it! I would say it runs true to size, in the sense that I now realize that my body is best suited for Tall sizes, and it is not strictly a ski/snowboard style (which might have longer dimensions). Docking 1 star seems fair, since that feels like a good score still, and hopefully a small motivation for this great brand to offer some other size ranges for us tall folk.

Exceeded my expectations

My experience so far with the coat has been phenomenal. The quality is top notch, and it looks and fits very well. The inner layer is warm enough for most cold/mildly cold days by itself, in conjunction with the outer shell is perfectly adequate for very cold weather. I would definitely purchase this again.

Lone Mountain 3-in-1

I wish it was advertised as more of a casual-wear jacket. The materials and overall quality are great but I cant say I will use it for cold-weather trekking as I'd hoped (no pit zips either).

Nice Jacket

Had this jacket for a couple of weeks during which we had record cold temps in our area. I thought it was mostly a spring/fall jacket, but it's surprisingly warm with the fleece liner and would be fine in winter. I don't like the struggle of getting my arms in and out of a fleece jacket, but the taffeta lining in the sleeves of the liner ... Read Moresolves that problem. My only suggestion is that Patagonia offer a lighter weight zip-in compatible liner or vest that can be purchased for use in cool weather.

Big fan of the 3 in 1, not sure why some people prefer layering unless it's because they just can't find the right combo. I live in the Midwest, so this is a great winter / snow jacket, but it also works really well as a warm quilted fleece for not-so-cold days. Great construction and excellent look.

This jacket is for my

This jacket is for my Son. He is a Californian and going to college in Northern Michigan where he is learning what real cold is. The Lone Mountain jacket is keeping him warm. He is very happy.
