    Product feature
    1. 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 10000 mm, the Alpinism Light jacket offers an extremely high level of waterproofing.
    2. Garment waterproofing
      The Alpinism Light was approved in a shower test under 100 litres of water / sq.m. / hour for 3 hours. This test reproduces the conditions of a heavy mountain downpour. For all additional information, consult the website
    3. 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 (such as with the Alpinism Light jacket)= highly breathable fabric / if 9 12 = slightly or not breathable fabric.
    4. Garment breathability
      On top of the main fabric's breathability, the choice of a mesh net pocket lining helps improve the jacket's thermal comfort. This lining prevents to build up of moisture than would a pocket made with the jacket's main fabric. Moreover this helps air to circulate through the jacket by opening the pockets. 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.
    5. Pockets
      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 equipped with an inner zip pocket.
    6. Zips
      The Alpinism Light jacket's main zip is a new generation zip offering the same waterproof properties as classic silicone zips (similar to 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.
    7. Hood
      The Alpinism Light jacket 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.
    8. 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:
