The Smartwool Knee Warmer is the perfect sport accessory to help you transition from season to season. Made of a blend of Merino Wool, nylon and elastic, the Knee Warmer is the perfect combination of warmth with one of the most efficient moisture management materials on the market. Seamlessly constructed, this Smartwool knee warmer provides maximum freedom of movement throughout your activities. A mesh knit ventilation zone at the back of the knee allows airflow to keep your legs from overheating. When you're running, the last thing you want is your knee warmers hanging out around your ankles. Which is why Smartwool has placed a non-binding welt at the thigh opening to keep the Knee Warmers in place. No matter the sport, guard your knees from the chill with the Smartwool Knee Warmer.
