The Portwest B121 Thermal Leggings create a layer of warmth around the lower body. The soft multi-fiber and knitted fabrics trap the heat. Elastic ankles and waistband provide a comfortable fit. These thermal garments are made from cellular weave (polyester & cotton) that wicks moisture away from the body, keeping the user cool, dry, and comfortable during work or your hobby. The garments are suitable for all levels of activity and can be worn as an additional thermal layer for cold weather workwear or as technical sportswear for added comfort and improved performance.
