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. Components with 2000 mm rating can resist 2000 mm of water pressure (which is roughly equivalent to a rain shower lasting 2 hours). With waterproofing greater than 10 000 mm, the Mountaineering light jacket offers an extremely high level of waterproofing.

Product's waterproofing

The jacket's waterproof was tested in a rain shower with 26 gallons of water / sqm / hour for 3 hours. This test reproduces the conditions of a heavy mountain downpour.

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 = slightly or not breathable fabric
The jacket's fabric has a RET of 8

Garment breathability\n

On top of the main fabric's breathability, the choice of including mesh lined pocket helps to improve the jacket's thermal comfort, whilst helping to create air flow inside jacket by opening pockets.


The jacket's hood size makes it compatible with a mountaineering helmet. It is height and depth adjustable according to your needs. A semi-rigid visor offers better forehead and eye protection. The high collar provides protection for the lower part of your face.

Pockets and Zippers

Outer shell: 2 large pockets that fasten with taped zippers. The pockets are positioned on chest, making it easier to get access to them when wearing a harness.
Inner jacket: 1 mesh net zipper pocket

Two-way front zipper allows you open jacket bottom up, to give you quick access to harness tie-in loop. The zipper pulls are easier to handle with gloves.

Product care

Machine wash at 86°F. Use washing powder, but not a softener. Close zippers and adjust cuffs before putting in machine. Reactive water repellency with adequate treatment after each wash. A whole range of specially made waterproof and breathable fabric care products are available in our Decathlon stores.
