Chillin' in Alaska wrote a review of Arc'teryx Atom SV Hooded Insulated Jacket - Women's on January 8, 2012
I've been wearing this jacket all winter here in SE Alaska. I do a lot of backcountry skiing. If the temp is below 20, this jacket is great. Warmer than that and I get too hot. Above 10 degrees all I wear is a single underlayer. I've found it to be plenty wind proof when up high out of the trees. I love how it breathes and wicks away any sweat from the skin up. It's always in my pack since it packs up so small. It fits great under my shell as well when the weather really turns on us.It's definately become my new go to jacket.
