Castelli's Nanoflex leg warmers are a testament to the brand's position as an innovative market-leader. Crafted from intelligent Nanoflex fabric, these cycling leg 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 then 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 leg warmers are finished with ankle zips and the signature Castelli branding to the lower leg. - L.R.


  • Castelli Nanoflex black leg warmers
  • Made from water-resistant Nanoflex fabric
  • Same breathability, stretch and warmth as Thermoflex warmers
  • Double-sided silicone grippers keep the warmers in place
  • Ankle zips for added ventilation
  • Great in every possible condition
  • Weight: 134g (Size L, manufacturer claimed)

Effective but weird fit

Total :


Water resistance works great and it water just beads off. Fit is a little weird. I'm 5'7", 165lbs and the length is fine, but the silicone gripper tends to slip down a little bit.

Excellent product

Total :


Bought these to match the arm warmers. Excellent product. Snug fit with Medium. (I'm 5"10, 156lbs.) Order/shipment process well executed.

Bigger than I thought

Total :


Solid looking leg warmers with plenty of silicone grippers. Cut very long as other reviewers have said. Going from sizing chart (I'm 181cm, 80kg) and noting Italian brands including Castelli are often smaller than UK/US brands, I bought a pair in size L. Unfortunately I had to return as they were too big and just wouldn't stay up after one short spin. So be careful with sizing. They didn't appear to be super-warm: which for mild (Sydney) winters is not a bad thing, and I had no opportunity to test water resistance which everyone says is great (they have an outside texture slightly different to other leg warmers - almost grainy).
