Description of Arc'teryx Easyrider Insulated Softshell Jacket - Women's:
Maneuver through gnarly routes and trails in total comfort when you zip up the Arc’teryx Women’s Easyrider Insulated Softshell Jacket. A durable Polartec Power Shield shell buffers against the wind while its fleece lining keeps you warm. Gusseted underarm seams prevent the Easyrider from riding up as you climb your favorite route. Don’t give wind an inch thanks to the interior storm flap and waist hem drawcord. Arc’teryx added a quick-dry chin guard to prevent chafing when your plans for the day include skiing from first chair to last.
This jacket is everything I ever wanted in a softshell. The Polartec Power Shield shell does an amazing job of blocking the wind while the soft, fuzzy, fleece interior adds enough warmth and thickness to give this jacket a substantial feel. I have worn this jacket on its own and layered. I think it is thick and warm enough to just need a shell, layering it under something like down or another insulated jacket would probably be overkill (although it depends on where you're going and what you'll be using it for). The drop tail in the back is a really nice feature, keeping you covered when you reach and bend. As for sizing, I got a medium (5'6", 135lbs) but think I would get a small if I was planning on layering this under a tech shell, it doesn't seem to be as tight as some other Arc'teryx pieces.
