Technical information

A highly breathable jersey

To determine whether a fabric is breathable, we measure its evaporative resistance (test based on standard ISO 11092). The lower its resistance, the more the fabric will let water vapour produced by the body escape, and therefore the more breathable it is.

Designed for steering

This jersey has been designed to offer great freedom of movement. You won't notice it whether climbing or descending. Its close fit and the colours we have selected guarantee a pure all-mountain style.
