Once you master the art of being comfortable in cold and wet weather, you can be happy just about anywhere you venture. Discovering the Sherpa Vayu Tights is a huge step to getting there. Made of 50% Merino wool yarn and 50% Primaloft Silver yarn they give you all the fantastic benefits of wool with enhanced performance on several fronts. Wool content pulls moisture off the skin while PrimaLoft Silver fibers push it on through the fabric. The result is versatile, breathable, odor thwarting comfort over a wider range of temperatures and conditions. You'll feel warm, even when wet the hybrid fabric dries 20% faster and is less absorbent than 100% wool.
