Waterproof and breathable. It's the ultimate solution - now available in our pinnacle running jacket. Per usual, it starts with a five-star fabric; in this case from the scientists at Schoeller, a global leader in high performance, technical fabrics. As a 2.5 layered laminate, Schoeller's e3 Protection Plus is designed specifically for high intensity output in high intensity weather. As you heat up, the textured interior keeps the fabric from sticking to your skin, while the specially designed laminate moves heat and moisture through the fabric while preventing rain and wetness from entering on the surface. To literally, seal the deal, all zippers are 100% waterproof, and every seam has been sealed, so no water can leak in. Add adjustability at the hood and hem, and it's the ultra lightweight water-proof shell that's ready for anything.
