2.5 layer PeakProof® fabric resists the elements and still breathes, keeping you dry without the crunch or crinkle of traditional rainwear. A fully seam-sealed construction seals out the elements and mechanical stretch moves with you through every climb and stride. Zippered underarm vents, a fixed hood and a brushed tricot chinguard deliver customizable comfort in changing conditions. Tuck it into a pack or bag as your reliable calm in the storm, however far you may wander.
