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 knee warmers take the guesswork out, meaning you get the best of both worlds. With vulnerable knees covered but fresh air cooling the lower legs. For cooler and damp conditions slip them on to provide extra warmth, 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 knee warmers come as a pair.

Castelli can officially only rate UPF 50+ Light Arm Skins at UPF 50+, but in their laboratory tests, they actually blocked 99.8 per cent of damaging UV rays. Using a polyester base they found this it is not only more effective than nylon at blocking UV rays but is also much better at keeping you dry, which means these skins are better in both cooler and warmer conditions. Castelli have kept the construction very clean to eliminate seams that can rub, and used double-sided silicone elastic to make sure they stay in place. They fold up extremely small, so they’re great to stick in your pockets for your next big mountain day.
Most warmers available are made from a nylon/elastane material and they tend to hold onto moisture, meaning they may be warm to start but they'll soon have you feeling chilly and damp when you get going. However, the Pro Seamless Knee Warmers use a polyester yarn, far better for dealing with sweat build-up while still maintaining excellent warmth. Just what you need for cool weather, hard training and intense racing. Thanks to the low weight, high stretch and seamless construction you'll barely notice them either. If the day warms up they'll fold up small and easy fit in a cycling jersey pocket.
