Pro Seamless Bike Knee Warmers

Designed with Team Ineos, the Pro Seamless collection from Castelli was designed to make a better group of warmers for arm, knee and leg. Others on the market are made with a nylon/Lycra blend that tends to hold moisture, but these use a polyester yarn for better moisture control. A pro rider favorite because they're crazy light and extremely warm for their weight, yet even in milder conditions, you don't overheat. They're so stretchy you'll hardly feel them on, yet when you take them off, they occupy a fraction of the space of traditional warmers in your pocket. Unisex sizing -- see fit tips for help.
