PeakWool™ is a midweight fabric constructed with Merino Wool, Tencel, Recycled Nylon and Spandex. The natural properties of Merino regulate body temperature, keep odors at bay and manage moisture to keep you dry. The addition of synthetic fibers increases softness, adds strength and elevates its wicking properties. PeakWool™ excels in cold temps by keeping your core warm and dry, while enabling heat transfer when the tempo picks up.
