A perfect barrier for wet and warmer conditions, this Sealskinz Wretham Sock is designed with a three-layer construction to achieve 100% waterproofing. A bamboo lining also helps to promote moisture control and comfort when the weather is warmer and flat toe seams prevent rubbing and blister. Zonal elastication and a four-way stretch add support to this closely fitting sock. Please note: this product is formerly known as the Unisex Waterproof Warm Weather Ankle Sock.
