Premium Merino Wool and Recycled Polyester for Stop-Start Mountain Movement The Crescent Fleece Half Zip locks out the chill when hammering up sun crisp trails, tucks neatly under your shell on cold glacier approaches, and slips on quick for when the sun sets at camp. Spun from recycled polyester and merino wool, it wicks sweat, is naturally odor-resistant, and moves and stretches like it's one step ahead. Plush microfleece on the inside locks heat in without the bulk, while a half-length zip dumps excess warmth instantly. Stretch-bound cuffs stay put while scrambling, and UPF 50+ shields you when the sky breaks. Made for the stop-start rhythm of mountain movement, the Crescent Fleece Half Zip delivers warmth when you need it and breathability when moving fast.
