Sealskins took the original waterproof sock and gave it a bamboo liner to help you stay dry and cool in the warmer months. With the added protection of Hydropstop™, these socks are designed to keep you dry and on the move in wet and warm conditions. Wet feet are super uncomfortable and can lead to all sorts of not-so-good things outdoors. Stay dry and comfortable in our Waterproof Warm Weather Mid Length Socks with Hydrostop™ while in rain, muddy conditions, standing in leaky waders, and through stream crossings. In serious downpours water can bead up on bare legs and calves and egress into the socks through the top. So Sealskins invented Hydrostop™, a silicone-like (although it is silicone-free) elastic taping around the inside cuff of the sock. This added protection reduces the chances of water dripping down your leg into your sock. Problem solved. Key FeaturesFeaturing a three-layer bonded construction that combines a bamboo lining for moisture control and comfort 100% waterproof hydrophilic membrane, and a durable nylon blend exterior with 4-way stretch for great fit and wearability. Particularly noteworthy is the unmatched breathability of the hydrophilic waterproof membrane to release perspiration steam and warm air from inside the sock. Designed with a seamless construction including hand-linked flat toe seams and the addition of elastic support on the ankle, heel and instep An ideal choice when there\\\'s a risk of getting your feet wet while cycling, commuting, hiking, fishing, or working outside.
