The Women's Patagonia Triolet Jacket is a non-insulated jacket for alpine exploring. The three-layer, durable, waterproof, breathable, and windproof GORE-TEX fabric with recycled polyester outer fabric protects against harsh winter conditions. A hood with a laminated visor and a reinforced brim effectively sheds water, and the two-way adjustment provides good visibility in poor conditions with or without a helmet. Stash additional items within the two Napoleon chest pockets with watertight zips and zipper garages, two welt front pockets, and one interior drop-in pocket. It's also equipped with a RECCO reflector for rescuers to triangulate your location in the event of an avalanche.
