Built from Polartec’s PowerDry, the Gauntlet is designed for optimal moisture management by efficiently removing water vapor from your skin and transferring it to your breathable outer layer (hard shell or soft shell) so it can easily diffuse through the membrane. It has a super-deep zip front, so you can quickly cool off if you get overheated. The end result is a warmer, dryer environment inside your gear which will make you and everyone around you much happier.
Polartec PowerDry is a mid-weight, high-stretch fleece with a polyester gridback. 4-way stretch fabric with a fast-wicking inner surface that is comfortable next-to-skin and transports moisture quickly to the outer face. 93% polyester/7% spandex; 230g/m2.
The Gauntlet is designed for insulation and moisture management, and it should be worn under a breathable shell when it's chilly. It won't do much for you in terms of cutting the wind (which is why you need the shell), but lots of our customers also wear the Gauntlet as a casual technical sweater.
