Additional information

Component 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 Alpinism Light jacket offers an extremely high level of waterproofing.
Garment waterproofing
The Alpinism Light was approved in a shower test under 100 litres of water / sqm / hour for 3 hours. This test reproduces the conditions of a heavy mountain downpour. For all additional information, consult the website
Component 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 the higher the fabric's breathability. We consider that if RET< 9 = highly breathable fabric / if 9<RET<12 = moderately breathable fabric / if RET > 12 = slightly or not breathable fabric. The Alpinism jacket has a RET between 9 and 12
Garment breathability
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 taped zip under the arms, helps to create air flow once opened, to further enhance ventilation. The adjustments at the hem (tightens with elasticated drawcord and toggle) and cuffs (riptab strap) allow you to adjust the air flow through these areas.
The pockets are positioned to be used as hand warming as well as for being accessible when wearing a harness over the jacket. The Alpinism Light jacket is also comes with a chest pocket and an inner zip pocket.
The Alpinism Light jacket's main zip is a new generation zip that offers the same waterproofing as the classic silicone zips (similar to the pocket zips) while being more flexible, which improves the jacket's compression when packed away. Plus, this zip is easier to handle, contributing to enhance its durability. The 2-way zip allows you to use a harness under the jacket. The zip pulls are easier to handle with gloves.
The Alpinism Light jacket's hood is large enough to wear over 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.
A rating for comparing products environmental impact
Product's environmental impacts are calculated throughout its life cyle and with different indicators. An overall ABCDE rating is performed to help you easily identify the products with the best environmental performance by comparing the same type of products with each other (t-shirts, trousers, backpacks,...). Decathlon is a committed stakeholder in this environmental labelling approach. To get more information:

    Orange is the new black!
    Completely waterproof, generous cut for movement. Really hard to find on the Decathlon website!

    I love my jacket!
    It has kept me dry in the heaviest rain and it has proved its versatility and breathability in very high winds but high temperatures, 2000m up in the Sierra Nevada of southern Spain.
    Depending on the badge (brand) you could pay two or three times more for a similar spec,
