About Castelli Nano Flex 3G Knee Warmers
The ultimate warmer. Choose Nano Flex for warmers that are great in dry conditions but also give some extra protection and warmth in wet conditions. Castelli invented the category of water-protective thermal fabrics, and Castelli's proprietary Nano Flex is often imitated but never equaled. No compromises for any conditions.

Features
Nano Flex: Exclusively engineered by Castelli. They take their thermal fleecy stretch Thermoflex fabric and coat it with millions of tiny 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.

Water-repellent thermal and breathable Nano Flex fabric

Flat-lock stitching with single seam

Double-sided silicone grippers to keep warmers in place

Temperature: 8°C - 20°C

About Castelli
Castelli are an Italian clothing manufacturer based in Fonzaso, Italy. In 1876 Vittore Gianni opened a clothing shop in Milan where he created clothing for AC Milan, Juventus, the Milan Ballet and cyclist Alfredo Binda. In 1935 Armando Castelli joined the business and four years later bought the company. He kept these high profile clients and continued making cycling clothing for riders including Fausto Coppi. In 1974 the scorpion logo was created and Castelli was born. Since then they've been at the forefront of innovation creating the first lycra shorts, coloured shorts and use of sublimation.

Jacob D. ★★★★★

The Nano Flex fabric is noticeably stretchier than my old neoprene warmers, making them much easier to get on and off. They've kept my knees perfectly warm during chilly morning rides, even when I got caught in a light drizzle.

Leo I. ★★★★★

Finally got these for the colder rides and they’re a game changer—the Nano Flex fabric really blocks the wind without feeling bulky. They stay in place perfectly even on long climbs, and the soft inner layer makes them comfortable against the skin.
