Wanted something for carrying up a route for a windy summit as well as for mountain biking. The biggest selling point on this for me was the length. I am 6ft with a long torso and this was noticeably longer than the Patagonia Houdini and other similar items. Also fits reasonably slim so its not too baggy when biking. Its also surprisingly water resistant!

As we were descending the Chief in Squamish, light rain approached and the temperature dropped. This was a perfect time to throw on my lightweight Squamish Jacket. This fits perfectly in a small 20L bag and doesnt seem to take up too much space. The DWR finish helped keep me dry and was my go to jacket all weekend. This is absolutely my jacket that I will take with me on multi pitch climbs as well.

I purchased this in a Medium and it fits great!

I love this jacket, I use it for all backpacking and adventures~~

Even if you have everything buy this! It's incredibly thin and water resistant! It packs up it the size of a sandwich! I have used it to avoid bugs & downpours while fishing. I have also used it as a knee pad while filming my kids graduation during sketchy weather. I always have this in my bag from May to October. It's that good! I just wish the logo was not reflective, i see the saftey aspect but it's not tactical. I have an Xl and its an athletic cut, so order 1 size up if your over 6' & 200 lbs.

and I prefer this over it, although I do have the previous version of this jacket, there's not really much difference in the fabrics between them. at 5.5 ounces, this jacket basically lives in my pack during the summer.

I love this jacket, I use it for all my climbing, biking, and hiking adventures!

FIT STUFF: I congratulate many Backcountry customers for (apparently) being Nordic marathon runners or whatever, but thought folks could also use another opinion from someone who isn't 6'3" with single-digit body fat. ;-)
My natural weight is around 175# (at 5'11"), and body-wise I skew dadlike; not pear shaped, but not suited for aggressively skinny/tapered cuts. However, when I bought this jacket this summer, I had crept well north of 195# (possibly above 200#?). At that time, the L jacket fit quite flatteringly. Worn over one or two light layers, it was perfect across my broader shoulders and chest, but also pleasantly skimmed my (roughly equivalent) middle, ending just below my waist/beltline (the slanting shirttail back helps visually slim/elongate the torso, too). The only aspect of fit which didn't work for me was the arms, which really are long but can be cuffed. For comparison with other garments, the torso on my L is about 25" across at the pits and 23" at the middle, with a roughly 21" shoulder, 29" back, and 38"(!) sleeve.
My feeling is that this jacket manages to look really sleek and athletic on people who are more tubular than triangular, when purchased in their size range.
I've since got my weight back down to under 185, and now the jacket looks a bit floppy, unless worn over a thicker layer like a sweater or sweatshirt. Having enjoyed the fit as someone pushing the upper limits of L (US standard, XL in more Euro cuts), I would feel confident buying it in a M now.
QUALITY STUFF: The fabric looks and feels very capable. It is soft to the touch and matte, with a subtle ripstop texture. To the degree I've used it rainy conditions -- light to heavy showers, and a few sustained storms -- it seems to be about as waterproof as can be expected, for something that must also be packable and breathable.
Actually, that breathability aspect is one of the the few cons of the jacket. It does let a fair amount of wind through, but still starts getting clammy pretty fast (about 15 minutes into any given activity, for me). I imagine that many users are going to be pulling it on and off as they hike, so this may not be as much of an issue. For me, a more urban user who doesn't have a handy backpack at all times, and would rather not carry their jacket in their hands every 30 minutes... Yeah, a little less than ideal. Vents in the pits or across the back would make all the difference, and I'm baffled that a jacket at this price point couldn't be bothered.
Most of the construction and design details are top-notch, though. There are a couple of cinch systems built in, and they are pretty easy to use. The zipper (especially the pull) is flawless. And the hood! I don't actually like hoods much, particularly how they blow around in the wind and obscure peripheral vision. But this one is weighted just right in the brim, allowing it to stay put surprisingly well while providing decent views to both sides.
OVERALL: I've had to replace a bunch of clothes as I gained weight, and now again as I've been reducing it. Given the slight cons, I'm still err, weighing whether this jacket will make the cut for replacement (although I will totally stash it in my car or maybe a camera bag, for emergency use). But, for those with a similar build to mine, who aren't sure whether it's *truly* true-to-size, I'd say go for it.

Use it on the craig, the hike, the ride, or the pub crawl home. Small as a granola bar. Keeps the wind at bay. Best used not stuffed up in a ball at the bottle of your pack...

I've had the non-hooded version of this jacket for a few years and find it incredibly versatile for its lightness, packability, and light yet breathable protection. I use if often in cool conditions where my output is medium and consistent like long summer days moving through the alpine. It is prone to snags, but I have taken a couple spills with not tearing. I will absolutely pick up the hoody when I can.

Bought this for my partner who first tried a couple of others. the material and fit made this his favorite. Its the perfect layer to have in your bag for that windy summer summit or quick unexpected rain storm.

This wind jacket has some advantages over others on the market: adjustable wrist cuffs (with the usual, awesome Arcteryx velcro tabs) allow me to push the sleeves up to my elbows or cinch them down. Even more importantly, it has a YKK vislon molded zipper (this is the only windshell, arcteryx or otherwise that I've found with this lovely feature), allowing for super easy one handed opening as well as quick easy closing. The single, simple, and tuckable waist hem works great. Some other little touches, like the brim of the hood make it a bit more livable. I got it in a bright color which makes it great for road running (high visibility). If i warm up to much on a run, its easy to stuff into its pocket on the move,

I mostly use this for cold weather running (30-45 F) and hiking. I sent the medium back to get a size Small. It is not long enough for me to use very easily under a harness, as it will be pulled up above the waist and make it a bit more difficult to access gear loops and so on. I wish they made this jacket a little longer/skinnier. I am 6'1" and the medium was excessively large and too long in the arms (I have an ape index of zero). It was very billowy and felt like I was drowning in all of the fabric. I know I'm a bean pole, but I found myself wishing (more than with most products) that this product was cut slimmer. Other changes that could be implemented are a smaller breast/stuff pocket. This jacket could easily fit into a smaller space than they allow for when stuffed, and frankly putting your big phone in this pocket feels a bit awkward, and far worse if the zipper is undone, so i don't ever put the size of this pocket to use anyhow.

In short, a windshell with the cut of a Patagonia Houdini, but with the materials (breathable fabric/vislon zipper, waist cinch) of the Squamish would be amazing. I would be psyched to see this product get tweaked to do just that.

I got it and thought I had the wrong jacket, it was so light! Also so soft and comfy like a shirt, that I didn't think it could shed water, so i put it on and stuck my arm under the sink.... wow.... like water off a ducks back... just rolled right off, water didn't even think about coming . through.

I did end up returning it thought to get an Atom SL to have some more insulation in the high mountains.

The arcteryx squamish hoody is an awesome lightweight jacket to keep you in your pack for just about any trip! Super lightweight and compressible so you won't even notice it's there, yet durable enough to stand up to some serious wear and tear.

Cool little ultralight jacket that packs down super small. And in true Arcteryx fashion, comes in a variety of cool colors. But it's still a niche jacket at best. I own this thing and literally have no other use for it other than hiking/backpacking. Any other activity where I might get rained on I would go a different direction. It has no hand pockets and has no pit dumps. So although I do enjoy the jacket, I'd only recommend buying it if you're looking for something super light and compact. If not, there are cheaper options within other brands that have more features (like pockets for a start. )

I will also say that it fits a little looser than most items in the Arcteryx brand. Not baggy, just not slim fit like normal.

No pockets on both sides ,Does not conform to the multi function localization .

No doubt Arcteryx excels in making the best jackets and backpacks. While Alpha SV is the all time king of Gore-tex jacket, this one is also very famous for its design and quality.

Feels great when wearing the jacket.

Really love it, lightweight enough.

But pls note that it's one size larger than other arcteryx jacket. It looks like trim fit in the picture, however, it's truely athletic fit, or even bigger. Almost all of my arcteryx jacket is M size and fit my body well, but for this squamish, I bought S size, but I still feel it a little bigger than I expect. I can even wear a cerium sl as a baselayer under squamish. But guys, it's a superlight jacket for running in autumn, I don't need a down jacket beneath the squamish right?

But if you get the right size, I think the squamish is a wonderfull one, an almost perfect jacket for mountain running in autumn, it would be real perfect if it could be updated with more pockets, for key, gel, phone or something

This jacket is great, packs down to the size of my wallet, keeps me warm in wind or light rain and very versatile. Throw in my fishing pack, backpack, running vest and wear to work. This jacket does it all and worth the price!
