This baselayer is designed to keep you dry and comfortable all day on the mountain—and anywhere you go after. Our signature lightweight PeakWool® fabric blends the natural warmth and moisture management of responsibly-sourced merino wool with synthetic fibers for the best in softness, stretch and durability. A deep drop zipper, flatlock seams and thumbholes layer with ease. The handy loop on the center back neck hangs to dry in the yurt or by the heater after the day’s riding is done. The perfect companion to our PeakWool® leggings for a full head-to-toe layering system.
