Our opinion

Castelli's best-selling leg warmers have been further improved for even greater efficiency!

Hubert D.

Textile expert and former professional runner



Nano Flex products have been part of the Castelli range for eight years now. Improvements are constantly being made to this kit, even though it already seemed perfect. Castelli products using the Nano Flex process are designed to keep you warm in dry weather, but they also offer extra protection and increased warmth in wet conditions!

The Nano Flex 3G Legwarmer is, of course, made from Nano Flex fabric, whose resistance to moisture and cold is well established. Note that Nano Light inserts have been incorporated in the flex zones to provide greater comfort and an optimised fit. There are also anti-slip silicone prints to ensure a perfect grip during exercise.

Technical specifications:

- Warm, moisture-resistant Nano Flex fabric
- Anti-slip silicone prints
- Recommended temperature range: 8° to 18°C
- Weight: 119g (per pair)
- Sizes: S, M, L, XL
- Colour: Black

    Very good product as always with Castelli. Stays well on the legs and allows the use of short shorts in mid-season. (Translated review)

    Worn during a long ride in the Pyrenees, dry weather and at night, I hardly felt the cold (3 degrees), even downhill. They slip on easily. A safe bet, very happy with my purchase. (Translated review)

    The old generation was very good, but this one is the BEST. Superior quality, warm and feels forgotten. In short, a second skin. (Translated review)

    Comfortable, they offer very good thermal protection and against humidity. Ideal for mid-season and during cool temperatures with an appropriate shorts. (Translated review)

    Comfortable, good protection against humidity. Skeptical at first, these leg warmers are ultimately pleasant on the bike for several hours. They don't move and don't bother. Normal size, unlike shorts which are smaller. I'm 1.70m and took M. And L for the shorts in this brand. I have adopted them. (Translated review)
