Are you looking for the toughest jacket in existence? Sweden-based Haglofs have combined Dyneema (the strongest fiber on earth) and the warmth of goose down for their V-Series jacket. The outer layer of the jacket is a Dyneema, polyester and polypropylene blend that is both extremely breathable, waterproof, while staying ultra-lightweight. That shell is then joined with 900 fillpower goose down insulation for a jacket thats not only durable and lightweight, but is also incredibly warm. The V-Series is a limited edition and available in two colorways.
