Castelli Pro Seamless 2 Knee/Leg Warmer - belgian blue 424

Together with our professional riders, we set out to develop a better line of seamless warmers. Other products on the market are made from a nylon-Lycra® blend that tends to trap moisture, but we knew we could achieve better moisture management with a polyester yarn. However, when working with polyester, it’s more difficult to achieve the right elasticity, shape retention, and consistent build quality. It took a year longer than we expected, but we’re all glad we didn’t give up.

These warmers are very popular with professional cyclists because they’re incredibly lightweight yet keep you extremely warm, without making you sweat even in milder temperatures. They’re so stretchy that you can barely feel them, and when you take them off, they take up only a fraction of the space that regular warmers would in your bag.
