The Fjallraven Polar Guide is such a warm comfortable waterproof jacket. You feel invincible in this. There are not any signs of wear, I wore it twice because I moved to warmer climates. The outer material is made from Fjallraven’s durable material G-1000 that can also be waxed for more protection. It’s insulated with Supreme Microloft, a synthetic insulation. There are so many pockets and they are of ample size for storage.
