The Arc'teryx Alpha FL packs down super small and is shockingly durable and comfortable. It has a full-length zipper, helmet compatible hood, and one large external chest pocket that offers quick access to abundant storage.
The women's version is lighter (9.5 oz. vs. 10.3 oz), offers a tailored waist and the blue color is lighter than the men's blue. They both also come in yellow and black. The listed retail price is the same for both versions: $399, although sale prices are available for both.
The Arc'teryx Alpha SV - Women's is tried and true body armor for mountain climbers. It's ideal for winter alpine climbing and long expeditions, but the shell can be used for everything and anything.
