This year I started traveling to snowboard and quickly learned that keeping weight and volume to a minimum while maximizing item versatility was extremely important. This sent me on a search for a mid-layer that fit these requirements. I ended up selecting the Atom as it could go under my shell for the coldest days and double as an outer piece for apres and about town on nicer days, while still pa snowboardsteve · arcteryx.com

Have been an LL Bean customer since my parents bought my clothes as a child. Have had a lot of LLB coats and only recently got this one. I've been missing out. Out of all the coats I've gotten - this one by far is my favorite. As they state - it's packable, repells water, blocks wind really well, and is very warm. I've been shocked about how good this jacket is. Has kept me warm in temps down to 1 James · llbean.com
