Basis Peakwool Midweight Half Zip

This essential baselayer is unlike any other when it comes to warmth and moisture management in cold conditions. The foundation of its peak performance and next-to-skin comfort is our proprietary PeakWool™ fabric, a powerful blend of soft yet resilient TENCEL™, nylon, and elastane fibers combined with the warmth and wicking of merino wool to deliver strength, comfort and stretch for everything from cold lift laps to off-season trail runs. Flatlock seams minimize friction and thumbholes enable easy layering.
