Arct'eryx for life!


I practically live in this hoody. It's great from fall through spring, handling intermediate temperatures well on its own but also adding some great warmth for cold days in the winter if layered properly. I especially love the sleeve cuff opening that is secure without being tight. I pretty much don't even notice I'm wearing it most of the time!
