As a versatile addition to our Alternative Line, the Alternative Essential Gilet has been entirely made from 100% recycled materials. Lightweight, the extremely dense weave of the recycled polyester offers the same high level of performance and wind protection as material made from virgin synthetics. Easily packable, its two-way zipper slides effortlessly, which makes ventilating simple, and taking it on or off a cinch. It’ll definitely keep the wind from penetrating to your chest, but the super light, breathable mesh on the back side will prevent overheating or moisture build-up.
