Waterproof garments can be constructed of a variety of different materials, each with very different characteristics. Some are natural, although most are synthetic. Some are coated, while others are laminated. For the purpose of this test, we selected nine different top-and-bottom combos made of “waterproof/breathable” (WP/BR) fabrics. These are the most popular fabrics used in waterproof hunting apparel, and for good reason. When you’re on the go in snotty weather, a garment’s ability to allow perspiration vapor to escape is nearly as important as its ability to repel precipitation.
