Seaslskinz's waterproof design gets a thermal boost for the winter season. The Trek mid length sock is constructed from Sealskinz’s Stretchdry technology and is woven from thicker merino than lighter models making it an essential item for long distance trekking in cold weather conditions.

• Stretchdry - waterproof and breathable fabric
• Thick weight - improved circulation in cold weather conditions
• Thicker merino wool - moisture control and comfort
• Elasticated ankle and instep - tensile support
• Y-gore heel construction - secure and comfortable fit
• Padded heel, toe and footbed - absorbs shock and guards against pressure and friction
• Hand linked toe closure - low profile seam to prevent rubbing
