SEALSKINZ Bircham Waterproof All Weather Ankle Length Socks - Grey & Grey Marl
Stay dry, protected and comfortable in all conditions with the Sealskinz Bircham Waterproof All Weather Ankle Length Socks.

Built using SEALSKINZ’s three-layer Aquasealz™ construction, these socks combine a durable Polycolon outer, a fully waterproof hydrophilic membrane, and a soft merino wool inner layer that naturally regulates temperature and wicks moisture.
