This minimalist jacket retains heat without weighing you down. Perfect for cold weather activities. It is made of Pertex Quantum®, a lightweight and crack-resistant recycled shell fabric that is insulated with Mimic SILVER, an insulation of recycled polyester with an excellent warmth-to-weight ratio. DWR-treated surfaces help repel water and dirt. You will also find hand pockets with zip for cold hands or small items.
