The Castelli Nano Flex 3G knee warmers are ideal for during all kinds of cold weather conditions. Thanks to the Nano Flex used, these knee warmers not only protect you from the cold, but also from splashing water and light rain. The material is water-repellent, keeping you dry a lot longer. It is important to note, though, that these knee warmers are not completely waterproof. Over time, you may still get wet from a heavier rain shower, for example.
The Castelli Nano Flex 3G knee warmers are also well-lined, keeping you nice and warm. This means you don't need to put on long trousers right away when it's on the cold side outside. The use of a single flat seam minimises the risk of irritation, resulting in optimal comfort. The double-sided silicone grippers keep these knee warmers perfectly in place while cycling.

As always Castelli a guarantee
- Mirco 22 May 2025
Really nice material, keeps warm just right and protects quite well from the rain, the seams don't feel... The only 'flaw' is that although I took size S they are a bit long (in length)

Good stuff, note: falls big!
- Sander 21 March 2022
Great quality, warm. Falls very large/. Have -apparently mistakenly- assumed that Castelli always falls small. Are for me, except for a strip of skin above the medium-high sock, long leggings. (Leg length 90)
