This garment has been subjected to a shower test using 60 litres of water/sqm/hour for 2 hours. This test reproduces the average conditions of a rain shower in the mountains.A waterproof rating of 2 000 mm means the fabric can withstand pressure exerted by 2 000 mm of water (the equivalent of a rain shower lasting for two hours).Waterproofing is expressed in schmerbers (for example: 2 000 schmerbers).
To assess the breathability of the fabric, the evaporative resistance, RET (test based on the ISO 11092 standard), is measured. The lower the fabric's resistance, the more water vapour generated by physical activity evaporates, and the higher the fabric's breathability. For example: RET < 9 = extremely breathable fabric / 920 = little or no breathability.
OUR ENVIRONMENTAL APPROACH
Because we are aware that we must act to preserve our playground, Quechua is committed to limiting the environmental impact of its products.
Today, this product is not eco-designed, but we work every day to make it more responsible: eco-design, repairability and sustainability are at the heart of our developments.
