Castelli's Nanoflex knee warmers are a testament to the brand's position as an innovative market-leader. Crafted from intelligent Nanoflex fabric, these cycling knee warmers bear all the cooling properties of a Thermoflex fabric in dry conditions to ensure you remain fresh and ventilated, yet when it begins to rain the NanoFlex fabric transforms to show its excellent hydrophobic qualities and repels water to keep you cool and dry. Double-sided silicone grippers keep these cycling essentials in place throughout your journey and the knee warmers are finished with ankle zips and the signature Castelli branding to the lower leg. - L.R.

I was a bit skeptical about these even after seeing a video detailing their water resistancy. I am very happy with these knee warmers, they really do keep the knees warm and dry. Bought the Castelli Claudio nanoflex bib shorts at the same time and they are also great. A good combo.
The NanoFlex warmers are as soft, stretchy and breathable as any others out there. Nothing unusual on any of those scores. Their real trick is that when water gets on them, rather than soaking in, it mostly just flows off.
Castelli don't claim that these are completely waterproof. Some water does get through, especially if it's hosing down, but most doesn't. I was genuinely taken aback - yep, taken aback - when I put these under the tap to check the claims. It doesn't look like it should work, but it does.
Of course, the sink test is okay as a party trick but it only counts if the fabric can repeat the performance out on the road... and it can. Road spray doesn't get in at all and neither does drizzle. Heavier rain can get through, especially in the areas that scrunch up behind your knees, but far, far less than normal. It's genuinely useful wet-weather protection, especially on this rainy old island where the next shower is never far away.
Really well made leg/knee warmers, put on the right way (they are oriented to accommodate knee bend) these are better than the average leg warmer! These sit high up the thigh so take into account if you have short legs (i.e.buy a size down)!
