Finally, the miracle jacket is here. At only 120 grams it offers full Gore-Tex® waterproof protection, the most breathable Gore-Tex® ever made and permanent water repellency — and it all folds down to fill just half a pocket. Now you don’t have to choose between a small jacket or a protective one to carry with you. We gave it a close-to-body race fit and functional details like the YKK® waterproof Vislon® zipper and a zipped opening to access your jersey pockets.
