7 DAYS STRAIGHT RAIN. NO WORRIES, FUNCTIONALLY SPEAKING. When mountain biking, deep puddles and muddy potholes can always appear out of nowhere – a challenge that adds to the thrill for the experienced mountain biker. Unfortunately, it’s a thrill that must be paid for with cold, wet feet. That is now a thing of the past, thanks to the specially-treated X-SOCKS® Mountain Biking Short Water Repellent. The water forms droplets that simply run off the water-repellent surface. Despite this advantage, the material is breathable and, along with the fantastic AirConditioning Channel®, provides a comfortable environment for your feet.
