Castelli Medio Long Sleeve Base Layer

The Castelli Medio Long Sleeve Base Layer is designed for riding in cool conditions where moisture management is more important than outright warmth. Perfect for temperatures between 4°C and 14°C, it offers the ideal balance of comfort, breathability and insulation.

Constructed from soft, sanded 190g polyester stretch fabric, this base layer feels smooth against the skin while ensuring sweat is quickly wicked away. The regular fit and crew neck design provide all-day comfort, with just the right amount of stretch to move naturally with the body.

Engineered as a mid-weight option, it bridges the gap between lightweight summer layers and heavy winter thermals. Long sleeves deliver extra coverage, making it the go-to choice for those changeable autumn and spring rides, or for layering under a jacket when temperatures dip.
