The Women's Patagonia Reversible Down Lightweight Sweater Vest is a versatile piece for centered warmth. No sleeves or collar to worry about here, while a boxy fit makes layering easy. Pair with a T-shirt, a long sleeve, or even a hoodie for instant warmth without the bulk of a jacket. It's reversible for a quick color change-up, and each side has pockets, zippered on one side, drop-in on the other. When the day gets warm, pack it into the left pocket and stuff it into your backpack for later.
