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.


Waterproofness is a fabric's ability to prevent rain water from passing through.
A fabric's waterproofing is determined by measuring its resistance to the pressure exerted by a water column, measured in mm (test based on ISO 811 standard). The higher the pressure, the more waterproof the fabric.
A material with a waterproof rating of 2000 mm resists the pressure exerted by 2000 mm of water (which roughly corresponds to a 2-hour rain shower).
