Discover men's and women's outdoor clothing made with 100% Royal Alpaca Wool. Soft next to skin, alpaca wool keeps you nicely warm on your adventures in nature. Hollow alpaca wool fibers provide odor resistance and breathability, ensuring you will stay clean and smelling fresh even on long trips, multi-day hikes, or during other physically demanding exercises and activities. Wear alpaca wool as a base layer or thermal underwear in winter, or as a single layer in summer.
