This jacket has been amazing ever since I first took it out of the box. It fits very nicely and even accommodates my helmet while snowboarding. As a member of the Gore Mountaintechs, I have had the opportunity to test numerous products with the Gore materials. I must say that the Pro-Shell is the most advanced gear they have in my opinion. It is impenetrable. I highly recommend this jacket to anyone looking for a solid outer layer when on the mountain.
