SealSkinz Mid Thermal Merino sock is an improved version of the Mid Thermal.

This sock is much warmer and extremely comfortable because of the ultra dense twist pile padding inside the Merino wool liner, which gives additional padding to pressure areas.

The socks can be worn next to the skin or with SealSkinz sock liners for even better thermal performance.

Inner sock - Merino wool and nylon lycra, a supremely comfortable, thermal and wicking/absorption layer for maximum comfort.

Waterproof membrane - 100% waterproof and breathable porelle membrane. Typical WVP 65%

Outer sock - elasticated nylon - faster drying, low absorption and excellent durability

Calf length - 100% waterproof protection up to the calf muscle. Seamless technology - no bulky stitched seams. New stretch technology - superb fit, excellent comfort.
