Our long-sleeve tops for men feature an extended body and sleeves for the ultimate athletic fit. Our men’s long underwear also offers moisture management and odor control on the fabric via Intellifresh(tm) powered by Silvadur(tm) technology. ColdPruf Quest men’s thermal tops are our most versatile layer; great for layering, casual wear, or active wear in all cold-weather environments, whether at home, on the job, or enjoying the outdoors.
