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.
