Arc'teryx crafted the women's Trino jacket for high-output in cold, windy, and damp conditions. It has windproof, breathable, and water-resistant GORE WINDSTOPPER on the chest and arms, while Atreus lines the back and underarms, delivering superior temperature regulation and performance stretch. The trim-fitting Trino features a drop back hem to provide rear coverage. Arc'teryx also equipped the Trino with a semi-auto locking front zipper slider, to prevent it from self-opening during runs. An internal floating lower hem can be tightened with a drawcord to block out cold drafts. There are two zippered hand pockets, one of which has an interior key pocket. The back has two stash pockets that are perfect for carrying your gloves.
