Castelli Nanoflex Knee Warmers

£30.00 £21.00

The Nanoflex Knee Warmer by Castelli is made from NanoFlex fabric which behaves just like Castelli’s Thermoflex fabric in dry conditions, but then provides unbelievable water repellency when it starts raining. Although it’s not fully waterproof, but it’s the most effective thing Castelli have ever made for keeping you comfortable in all conditions.
