Waterproofing of the garment
This clothing was tested in a shower trial using 60l/sqm/hr of water for 1 hour. This test reproduces the average conditions of a rain shower. The fabric of this jacket is water repellent, i.e. water runs off its surface without getting absorbed. This prevents the fabric from soaking up water and keeps it lightweight and breathable. The water repellent property is achieved by treating the fabric's exterior. In addition, we taped the main seams that are most exposed to the rain.
How to maintain the waterproof feature of your jacket in the long term
In order to maintain good waterproofing over time, the fabric's water repellent properties must be regularly reactivated. We recommend doing this every three washes or after a dozen uses in the rain. The waterproof property is easily reactivated by warming the fabric: either in your tumble dryer or with a hair dryer, for example, over a relatively short period. Rinse thoroughly after washing.
Waterproof rating expressed in mm or schmerber
We measure a fabric's resistance to water pressure, expressed in terms of the height of a water column in mm (based on the ISO 811 standard). The higher the water pressure, the more waterproof the fabric. A component with a waterproof rating of 2,000 mm can therefore withstand the pressure exerted by a 2,000 mm water column.
To find out whether a fabric is breathable, we measure its evaporative resistance of the textile (RET) based on the ISO 11092 standard. The lower the fabric's resistance, the more water vapour generated by physical activity can escape, and the higher the fabric's breathability. - RET < 9 = extremely breathable fabric - 9 < RET < 12 = very breathable fabric - 12 < RET < 20 = breathable fabric - RET > 20 = little or no breathability
How to choose your waterproof jacket according to your activity and your sporting effort
During sports activity, the extent to which we perspire depends on the intensity or duration of the physical effort. If the breathability of the fabric is not adapted to your type of physical activity, the perspiration vapour condenses inside the jacket. You will feel damp inside: this is not rain coming through, but perspiration condensing. You therefore need to choose a rain jacket according to your type of physical activity. This jacket is designed for 2-hours hiking at a max speed of 5 km/h.
A score for comparing products' environmental impact
On a scale from A to E, this jacket scored a C. The environmental impacts of our products are calculated over their entire life cycle. A score is given to each product so that you can easily identify the more eco-friendly products within a particular family (T-shirts, trousers, backpacks). Decathlon is a voluntary supporter of this environmentally-friendly labelling approach.
Working towards more environmentally-friendly dyes
We take care of our planet to preserve our natural playground for hiking. Given that, for this jacket, we have only mastered the new dyeing process above for some of the colours, we have opted for a material made entirely of recycled polyester fibres for the other colours (main fabric in turquoise and red and the lining in navy and red). As a result, we have reduced our environmental impact on all the colour versions.
Additional recommended products
Wear the NH500 Waterproof over-trousers to protect your lower body as well. You will then have a comprehensive protection system that is very effective against the wind and showers. And, first and foremost: from 2019, we will also start using this more eco-friendly dyeing process on these overtrousers!
Our hiking jackets and waterproofs are guaranteed for 2 years. Our commitment? To offer you long-lasting products that you can use on all your country walks and strolls. Because the products we love the most are those that have a story behind them and plenty of life in them yet!
We recommend that you always dry this jacket thoroughly before storage.
All our models are tested by users representative of our target market in conditions identical to those you encounter yourself when using them. We believe that carrying out 'real-life' testing is the only way to design and continuously advance the technical relevance and design of all our Quechua products.
