If you're racing or training in mild but often changing conditions, it can be difficult to decide whether to cover the legs or not. The NanoFlex 3G leg warmers take the guesswork out, meaning you get protection in when it's cooler but extra comfort as the day warms too. For cooler and damp conditions slip them on to provide extra warmth for your legs, and wet weather protection should the clouds break. If the sun shows up, they're easy to take off and stow in a back pocket. They're the ideal companion to wear with your thermal winter bib shorts. This 3rd generation of NanoFlex is better than ever thanks to the 3G weave that provides extra warmth, improved water resistance and features a nanotechnology microfilament mechanical water repellent finish combined with a short-chain chemical durable water repellent (DWR) finish for class-leading water resistance. Castelli's NanoFlex warmers collection are used by Team INEOS, often copied but never bettered. Note: The Castelli NanoFlex 3G leg warmers come as a pair.

Race-tuned warmers engineered to the specifications of our WorldTour riders for uncompromising comfort and premium finishing details. Our test riders and WorldTour athletes requested some changes to our standard Spring Fall Leg Warmers. This is the result. The OSMOS Medium material is the same used in our premium winter jackets and tights and it provides better temperature regulation and durability than the RX Light material in our standard Spring Fall warmers. The RS warmers also include ankle zips so they’re easier to strip in the saddle and increased grip ensures they stay in place when you need them. 63%PA 20%EA 17%PL

Race-tuned warmers refined with feedback from our WorldTour riders for uncompromising comfort warmth and ease of removal. Assos updated the fit to further reduce pedaling restriction and increase thermal protection on the outside of the upper thigh into the hip area. We also added a zippered ankle which makes the warmers easier to strip and stow while in the saddle. On days you wear them for the entire ride these new warmers ride more securely courtesy of our skinGrip Finish a low-bulk silicone grip that allows for seamless layering and raw cut hems.

Our lightest knee protectors engineered to provide both UV protection and ultralight insulation. Excels at moisture transportation actively manages skin temperature and protects against the sun’s rays on bright summer days. A new textile and construction virtually eliminate the bunching and restriction common with knee protection providing a high-stretch comfortably compressive solution to everything from UV exposure and a glistening sheen of perspiration during summer rides to the lingering chill and gradual dull ache of exposed knees in early fall and late spring. Regardless of the season every ride benefits from aggressive wicking and the material serves as a corrective to the temperature cooling in the heat and warming in cool conditions. 78%PL 15%PA 7%EA
An update to the classic leg warmer featuring the return of our anatomical cut and our most pedal-friendly thermal material for dry cool conditions. Though they’re deceptively simple in theory not all leg warmers are created equal. Our latest model proves the point with a return of our anatomic wrinkle-free shaping and a new lightly compressive material that moves through the pedal stroke without shining white when stretched across the knee. 86%PA 14%EA
