The ArcticShield Heat Echo Loft Vest is an extremely weather-resistant outerwear piece. The stitchless quilted design features Retain Active. This technology retains your body heat, providing warmth, in an extremely thin, breathable, lightweight material, allowing you to move freely. The Heat Echo Loft Vest features an insulated collar; deep zippered chest pockets; a front zipper with inner storm flap; large zippered hand warmer pockets; and an adjustable draw cord waist that cinches tight to keep the cold out. The vest is water resistant, breathable, windproof, and lightweight. ArcticShield Retain provides warmth where you need it most, while still allowing you room to move - because it provides less bulk. This heat retention technology captures greater than 90% of body heat, and returns it back to your body, keeping you warm and comfortable.
