Product waterproofing
Waterproofing is the ability of a fabric to stop the passage of rain. We measure a fabric's resistance to water pressure expressed in mm water column (test based on ISO 811 standard). The higher the value, the more waterproof the fabric.
A component with a waterproof rating of 2000 mm can withstand the pressure exerted by 2000 mm of water (roughly equivalent to a 2-hour shower).
The waterproof rating of our Ultralight rain jacket is 2000mm.
Component breathability
Pour savoir si un tissu est respirant, on mesure sa résistance évaporative (test basé sur la norme ISO 11092).
Plus la résistance est faible, plus le tissu laisse s’échapper la vapeur d'eau générée par le corps en activité, donc plus il est respirant.
Par exemple : RET < 9 = tissu extrêmement respirant
Le RET de notre coupe pluie Ultralight est de 6.
Product tests
Our team of product designers is based in Lille at B'TWIN VILLAGE (France). All year round, we design and develop beautiful, simple and technical products for cycling.
We then ruthlessly test them in the field with users, because we're convinced that only real-life situations, as you'll experience them on your bike, can enable us to constantly improve.
Maintenance tips
Hand wash. Turn product inside out. Use little washing powder. Do not use fabric softener. Hang to dry in a warm, well-ventilated place. Do not tumble dry. No dry-cleaning. Do not use chlorine. Do not place on a radiator.
