This lightweight jacket is designed with Trespass' Tres-Tex fabric, giving it up to 5000mm waterproof protection. Taped seams stop water from leaking through the panels. In addition to being windproof, it has a breathability of 5000mvp that helps air move between the layers so you stay fresh inside even while you work up a sweat. Back yoke ventilation allows air to circulate so you stay cool on warmer days. Two pockets provide handy storage. The hood and hem are adjustable with drawcords and toggles, and the cuffs are fully elasticized. This jacket can be rolled up and packed into a small pouch (pouch is included). If the rain starts suddenly, you’ll have a protective waterproof layer on in seconds.
