Introducing the Nano Flex 3G Knee Warmers, the ultimate solution for cyclists seeking warmth and protection in any weather. These knee warmers are engineered to excel in dry conditions while providing additional warmth and moisture resistance when wet. Our exclusive Nano Flex fabric is a game-changer, offering waterproof thermal clothing that you can rely on.

Millions of tiny nano filaments create a surface that repels water, allowing droplets to bead up and roll off without soaking the fabric. Whether you’re riding in light rain or chilly temperatures, these knee warmers ensure you stay comfortable and warm.
Features include:
- Nano Flex waterproof, thermal, and breathable fabric
- Flatlock stitching for durability
- Double-sided silicone grippers to keep the warmers in place
