We measure a fabric's resistance to a water column, in mm (based on the ISO 811 standard). The higher the water pressure resistance, the more waterproof the fabric. Components with 2,000 mm rating can resist 2,000 mm of water pressure (which is roughly equivalent to a rain shower lasting 2 hours). With waterproofing over 30,000 mm, the Mountaineering jacket offers an extremely high level of waterproofing.
The Mountaineering jacket was approved in a shower test under 100 litres of water/m²/hour for 3 hours. This test reproduces the conditions of a heavy mountain downpour.
To find out whether a fabric is breathable, we test its evaporate resistance or RET (based on the ISO 11092 standard). The lower the fabric's resistance, the more moisture generated by an active body is evaporated and therefore the higher the fabric's breathability.
We consider that if
- RET < 9 = highly breathable fabric
- RET > 12 = slightly or not breathable fabric.
The Mountaineering jacket has a RET between 9 and 12
On top of the main fabric's breathability, the choice of including mesh lined pocket helps to improve the jacket's thermal comfort, while helping to create air flow inside the jacket by opening pockets.
The taped zipper under the arms helps to create air flow once opened, to further enhance ventilation.
Adjustments at the bottom of the jacket (closure system with drawstring and cord lock) and wrists (Velcro) let you choose how much air to let in.
The pockets are positioned to be used as hand warmers as well as to be accessible when wearing a harness over the jacket. The Mountaineering jacket also comes with a chest pocket and an inner zipper pocket.
The Mountaineering jacket's main zipper is a next-gen zipper that offers the same waterproofing as classic silicone zippers (similar to the pocket zippers) while being more flexible, which improves the jacket's compression when packed away. Plus, this zipper is easier to handle, which helps to make it last longer. The 2-way zipper allows you to use a harness under the jacket. The zipper pulls are easy to use with gloves.
The Mountaineering jacket's hood is large enough to wear over a mountaineering helmet. Its height and depth are adjustable to suit your needs. A semi-rigid visor offers better forehead and eye protection. The high collar provides protection for the lower part of your face.
Score to compare the environmental impact of products
The environmental impact of the product is calculated over its entire life cycle and using various indicators. An overall score (ABCDE) is attributed to help you easily identify the products with the best environmental performance by comparing products of the same type with one another (T-shirts, pants, backpacks, etc.).
Decathlon chose to apply this voluntary environmental labelling scheme.
