SealSkinz Waterproof All Weather Mid Length Sock with Hydrostop


5.0 (1 review)

This is the waterproof sock that started it all. The Waterproof All Weather Mid Length Sock with Hydrostop is the original SealSkinz 100% waterproof, windproof and breathable sock with the addition of Hydrostop™ to stop water on your legs from running down into the sock. These socks are made with a 3-layer bonded construction that fuses a waterproof hydrophilic membrane between a moisture-wicking, warm premium Merino wool lining and a 4-way stretch nylon exterior to keep you dry and comfortable. Keep your feet dry and warm when you’re out adventuring, be it hiking, cycling, commuting, hunting, fishing or working outside.

    These have been amazing with trail runners in snow. Keep my feet warm, dry and blister free.

    Wouldn’t recommend outside of Autumn and Winter.
