Ben Juneauwrote a review of Arc'teryx Squamish Hooded Jacket - Men's on May 24, 2018
Familiarity: I've put it through the wringer
Fit: Runs large
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.
