This garment has been validated in a shower test under 60 L of water / sqm / hour for 2 hours. This test reproduces the average conditions of a rain shower in the mountains. A component with a 2000 mm waterproof rating is therefore resistant to the pressure exerted by a 2000 mm column of water (which roughly corresponds to a 2-hour downpour). The waterproof rating is expressed in schmerbers (for example: 2,000 schmerbers).

To find out whether a fabric is breathable, we test its evaporative resistance or RET (based on the ISO 11092 standard). The lower the fabric's resistance, the more water vapour generated by physical activity is able to escape, and the higher the fabric's breathability. For example: RET < 9 = extremely breathable fabric / 9

The product's environmental impact is calculated over its entire lifespan, using various indicators. An overall score is assigned from A to E to help easily identify the most eco-friendly products by comparing products of the same type (T-shirts, trousers, backpacks etc). Decathlon is committed to displaying environmental information about its products. For more information: http://sustainability.decathlon.com/
