The Castelli Nanoflex+ Knee Warmers improve on Castelli's industry-leading Nanoflex technology.

The Nanoflex+ design adds inserts to the back of the Nanoflex fabric that boost flexibility and also improve water resistance. Silicone grippers help to maintain the perfect fit while the 8 to 22˚C temperature range makes these warmers highly versatile.

Castelli Nanoflex+ Knee Warmers

Building on a legacy of performance, the Castelli Nanoflex+ Knee Warmers boost comfort and insulation while also offering water-resistance. NanoFlex fabric provides comfort, insulation and breathability alongside a level of water-resistance that is certainly appreciated in light showers.

A new addition to these knee warmers is the Nano Light inserts on the back. These inserts provide extra stretch and comfort without compromising warmth or water-resistance. Double-sided silicone grippers keep the knee warmers firmly in place under your bib shorts and the wide 8 to 22˚C temperature range makes this one of the most versatile items of clothing in any cyclist's wardrobe.
