Notre avis

This base layer accelerates moisture absorption and evaporation during rides in hot weather. It is lightweight, comfortable and particularly effective.

Hubert D.

Textile expert and former professional runner

Castelli has focused on lightness and performance in the design of this base layer. It is made from Magic Mesh, a fabric that is extremely effective at wicking away sweat. Its lycra-free composition also helps to speed up moisture evaporation.

Technical specifications:

- 100% polyester Magic Mesh fabric
- Lightweight, minimalist construction
- Reduced seams for greater comfort
- Colours: White, Black
- Sizes: S/M – L/XL – XXL

pleasant under jersey for hot weather, disperses sweat well without warming effect, just the right size but fits snugly (1.86, 80 kg size L/XL). (Translated review)

Very pleasant to wear. With its mesh, it does not retain heat. (Translated review)
