Castelli Nanoflex Knee Warmer

Castelli Nanoflex Knee Warmer

Castelli Nanoflex Knee Warmer: Warm breathable Knee warmers with Castelli's advanced Nano silicone treatment for fantastic water resistance. NanoFlex fabric behaves just like Thermoflex fabric in dry conditions, but then provides unbelievable water repellency when it starts raining. Castelli don't claim that it's fully waterproof, but it's the most effective thing we've ever made for keeping you comfortable in all conditions. It's just barely short of a miracle. Nano Flex Exclusively engineered by Castelli, thermal fleecy stretch Thermoflex fabric is coated with millions of tiny silicone nanofilaments to create the most water-repellent fabric finish ever. Drops of water stay as spherical balls on top of the fabric or bounce off the fabric without leaving a trace. The silicone nanofilaments also trap a layer of air between them for excellent insulation and prevents water droplets from soaking through the coating to the fabric underneath. Water-resistant nanoflex fabric Same breathability, stretch and warmth as Castelli standard thermoflex warmers Great in all conditions
