Product's waterproofing
The jacket's waterproof was tested in a rain shower with 100 litres of water / sqm / hour for 3 hours. This test reproduces the conditions of a heavy mountain downpour.
Fabric waterproofing
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. A component with a 2000 mm waterproof rating can withstand 2000 mm of water pressure (which is roughly equivalent to a rain shower lasting 2 hours).
With waterproofing greater than 10,000 mm, the Alpinism Light jacket therefore offers a very high level of waterproofing.
Fabric breathability
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
- 9 < RET < 12 = breathable fabric
- RET > 12 = slightly or not breathable fabric
The Alpinism Light jacket's fabric has an RET of 8.
Hood
The jacket's hood size makes it compatible with 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.
Pocket and Zip
Outer shell: 2 large pockets that fasten with taped zips. The pockets are positioned on chest, making it easier to get access to them when wearing a harness.
Inner jacket: 1 zip pocket
Two-way front zip allowing opening from the bottom and a quick access to harness tie-in loop. The zip pulls are easy to use with gloves.
Product care
Machine wash at 30°C. Use liquid detergent without fabric conditioner. Close zips and adjust cuffs before putting in machine. Restore water repellency using a suitable treatment with every wash. A whole range of specially made waterproof and breathable fabric care products are available in our Decathlon stores. Using them will allow you to get the most out of your product throughout its life.
