Component impermeability
This garment has been validated in a shower test under 60 l of water / m² / hour for 2 hours. This test reproduces the average conditions of a mountain shower.
A component with a waterproof rating of 5,000 mm can withstand the pressure exerted by 5,000 mm of water (roughly equivalent to a 2-hour shower).
Impermeability is expressed in schmerbers (for example: 5,000 schmerbers).
Component breathability
Pour savoir si un tissu est respirant, on mesure sa résistance évaporative RET (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, et plus il est respirant. Par exemple : RET < 9 = tissu extrêmement respirant / 9 < RET < 12 = tissu très respirant / 12 < RET < 20 = tissu respirant / RET > 20 = tissu peu ou pas respirant.
COMPONENT RESISTANCE
We carry out a number of laboratory tests to guarantee optimum resistance: an abrasion and rub resistance test to ensure that fleeces do not pilling, a colorfastness test to check colorfastness and resistance, and an ageing test to certify that repeated washing does not alter the fabric's properties, behavior, thickness or appearance.
PRODUCT DESIGN: OUR EXPERTISE
Our worldwide design center Quechua is based in Passy, at the foot of Mont-Blanc in Haute Savoie.
This location makes it a real meeting place for our teams (designers, product managers, engineers...) and outdoor sports enthusiasts.
A great asset for designing your mountain hiking products, and for providing you with all our expertise.
