Summit Gilltek

The Summit Jacket provides warmth when you need it and breathability when you need it in lightweight, single-use insulation. From chilly days at your favorite resort to cold-weather hikes and walks, there's no need to remove layers with this versatile essential jacket. Gilltek regulates internal temperature by releasing uncomfortable heat when you're working hard and trapping it when you stop. Articulated elbows maintain an ergonomic fit, and a hidden stuff sack lets you stow the jacket or even use it as a travel pillow.
