This is a great product. It's waterproof yet amazingly breathable. I love how the material feels, its soft and doesnt stick to your skin. It's also well built, and looks like it will withstand years of use. I've run in the snow in 30 degree weather and I've mountain biked in 55 degree pouring rain, and both times I stayed dried and it doesn't hold in the sweat. I really love this jacket, great for those who want to do cardio in the rain.
