I'm a bigger dude, but this shirt is pretty tight. Large in Arc'teryx is my normal size and I almost wish I got an XL this time. The neck is not constricting though - so I am…

I've had Arc'Teryx wool, Icebreaker, Smartwool, and a handful of the other 'big names' and hands down Arc'Teryx makes the best wool. It's the strongest, lasts the longest, loo…

Warm and comfortable, not an itch anywhere. They have an odd quality in that they are toasty in a cool room and out in the icy world. Very well stitched too - long underwear…

For the taller than your average Joe such as yours truly (6'6", 36" inseam) it is so pleasant to wear a product which actually fits correctly. The fit is only half of it, how…

These long johns rock. they fit really well but don't pull hairs or bunch up like wool or cotton. The fabric dries fast which is handy when winter adventuring. Plus you feel f…

Picked this up a few weeks back. I was hesitant to spend so much on just a baselayer wool top, but I can tell you now that it is worth the price. Holds heat well & the fit is…

I own a lot of Arc'teryx gear, but this is one of those products that I always viewed as being absurdly overpriced, until I bought one. It's probably the most versatile & com…
