Waterproofing 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. 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). Our Ultralight jacket is waterproof up to 2000 mm.

To determine whether a fabric is breathable, we measure its evaporative resistance (test based on standard ISO 11092). The lower its resistance, the more the fabric will let water vapour produced by the body escape, and therefore the more breathable it is. For example: RET < 9 = extremely breathable material The RET of our Ultralight showerproof jacket is 6.

Our team of product designers is based at the B'Twin Village in Lille (France). All year round, we conceive and develop new products that are easy to use, look great, and have the technical features needed for your cycling experiences. They are then mercilessly put to the test by users in the field, as we are convinced that only by subjecting our products to real world conditions, such as the ones you will experience on your bike, can we continuously improve them.

Hand wash only. Turn the garment inside out. Use minimal laundry detergent. Do not add softener. Line dry in a warm, ventilated area. Do not tumble dry. Do not dry clean. Do not bleach. Do not place on a heater to dry.

A product's environmental impact is calculated for its entire life cycle using various indicators. An overall rating (ABCDE) is given, allowing you to easily identify products with the best environmental performance by comparing similar products to each other (T-shirts, trousers, backpacks etc.). Decathlon openly displays the environmental ratings of its products. To find out more: http://sustainability.decathlon.com/
