Technical information

Product warmth

A product's ability to protect from the cold. It depends on the material's thermal resistance and how much air can pass through it. The higher its thermal resistance, the more the product retains the heat produced by the body while cycling.

Component breathability

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.

Care tips

Machine wash at 30°C. Wool cycle. Turn the product inside out and fully close the zip.
Do not add softener. Hang to dry in a warm, ventilated place.
DO NOT TUMBLE DRY as this may deteriorate the component.
Do not dry clean. Do not bleach. Do not place on a heater to dry.
