The Echo is perfect for high-exertion activities and hot weather, a sun hoody made for the Eastern Sierra. The soft fabric breathes, wicks moisture, and dries quickly. Raglan sleeves and flat-seam construction reduce chafing. It is treated for odor, and UPF 15 protection helps prevent sunburn when summiting the high peaks. A zippered stealth pocket makes this the only layer you need for adventuring all day in the High Sierra.
