Our lightest, thinnest, waterproof sock.
The original, ankle length, military-trusted Wretham sock. 100% waterproof, our lighter socks are perfect for running, hiking or any activity. The Aquasealz™ membrane releases body-generated heat and moisture, while denying the entry of external elements. Natural bamboo lining for added moisture control. Handcrafted in the Sealskinz factory in Norfolk. A sock for warm, potentially wet weather.
Outer – Extra-durable nylon exterior, with 4-way stretch for an optimal fit.
Mid-Section – Aquasealz™ membrane is 100% waterproof. Also highly effective in the release of moisture vapour from inside the sock.
Interior – Bamboo lining for added moisture control.
A seamless construction, with elastic support on the ankle, providing a close fit.
Lovingly handmade in our Kings Lynn factory, under the guidance of Robbie Greenacre, head of innovation and technical development.
