The Rohan Merino Union 200 Leggings are technical base layer bottoms designed for cold-weather activities. Constructed from a hybrid blend of merino wool and polyester, these leggings combine the natural thermal regulation and odor resistance of wool with the fast-wicking and durable properties of synthetic fibers. The fabric is engineered to provide warmth while managing moisture during high-output movement. These leggings feature a flat-locked seam construction to minimize friction against the skin and a comfortable elasticated waistband.
