It is the first Arcteryx gift to my wife. She LOVE IT! It can be rolled up in a small bundle and the weight is negligible. It is very easy to bring for travel and won't occupy your bag. My wife is 1.6m and 52kg. Sleeve of the S size is a little bit long but acceptable.
"AWESOME! Instant warmth. Looks great. Worth the bucks."
This shirt was a gift and I couldn't believe the price tag...until I put it on for the first time! It fits great, looks great, but best of all, it works. Took it for a one-night backpack on the SC Foothills Trail; had cold drizzle/sleet all day followed by a cold front that night. We were on a ridge with high winds and a low of 23 degrees. Wore this over an undershirt to sleep in (I have a 20-degree down sleeping bag) and was toasty all night. No need for any more layers. Kept it on for the hike out and was comfortable - warm but not sweaty. I am 5'4", 112 lbs, and a 36D and the medium is perfect. Wish I could have it in every color!
"Just what I needed for winter in northern Michigan."
I'm so happy I bought this!! It is a great layering piece-- not too heavy or bulky. Goes great along with other layers. I have worn it to the climbing gym and it moves well and when i do my stellar climbing moves. And of course it is soft and cozy too!
