What Our Gearhead(R) Experts Are Saying:"I wore this on a long day above treeline with basically no shade for hours. The fabric stayed breathable even as I was sweating on the climbs, and the thumbholes kept my sleeves from riding up the whole time."Long days in the sun ask a lot of a base layer, and the HIMALI Eclipse Sun Hoodie is built to keep up without weighing you down. Pull it on before a full day above treeline or out on open water, and the 4-way stretch fabric moves with you through every reach and stride while UPF 20 protection keeps the sun from turning the day into a liability. Moisture wicking and fast drying properties keep sweat from lingering against your skin, while thumbholes anchor the sleeves in place so you're not constantly readjusting. A soft, zipper free side pocket keeps small essentials within reach without adding bulk or noise to an otherwise low profile layer.
