Product warmth

Ability of a product to offer protection from the cold.It depends on the material's thermal resistance and air permeability.The higher the thermal resistance, the more the product keeps the heat produced by the body while cycling.


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 vapor produced by the body escape, and therefore the more breathable it is.
For example: RET <9 = extremely breathable fabric.
