For mountain mavens who run chilly, this midweight tight will be your best friend when the cold tries to keep you inside and all you want to do is move. The foundation of its performance and next-to-skin comfort is our proprietary midweight PeakWool® fabric, a powerful blend of soft yet resilient TENCEL™, nylon and elastane fibers combined with the warmth and wicking of 56% merino wool to deliver strength, comfort and range of motion during cold days on the mountain.
