Abstract
Waterproof, breathable garments and methods of making are provided. The garments may include a laminate of a seamless ePTFE membrane and at least one textile. The garment is conformable over a range of sizes, and may be shaped to fit numerous sizes and shapes of forming molds. The ePTFE membrane may shrink to fit, or, alternatively, be stretched to fit, a mold having a desired size to form a garment. Such a conformable ePTFE membrane may allow for forming multiple sizes of garments with various sizes and shapes of molds. In embodiments where the ePTFE membrane is seamless and continuous, the garment eliminates the need for a waterproof seam tape, which is conventionally used to make garments waterproof.
