Castelli Pro Seamless Leg Warmer Keeping Your Legs Warm in The Cold Castelli worked with the pro cycling team, Ineos to develop lightweight warmers that provide exceptional warmth and moisture management. The Castelli Pro Seamless Leg Warmer is constructed using a unique polyester/nylon/lycra construction, making them comfortable to wear as long as you need and are stretchy enough to provide a good fit for most. These leg warmers are the ideal choice for early morning rides in cool to mildly warm weather and are super compact so you can take them off and fold them up and stash them in your rear jersey pocket whenever they're not needed.
