Next size up

Ordered the exact size but was far too tight because it’s going over your original trousers so ordered next size up more room around the waist and leg for your wellies or boots.

Great product

Can’t fault the product or the supplier

Very waterproof

I bought these the day before doing a 10.5 mile charity walk. They kept me 100% dry during Storm Aiden, very impressed! Did the job at a bargain price. Strongly recommended.

Hi Brian,

Thank you very much for your feedback. It helps us to keep improving in our services. We are sorry you didn't feel your experience in our store was a 5 star one. We will pass your feedback on to the relevant team!

Have a nice day!

Team Decathlon, Braehead.



Very basic for hill walking but kept me dry whilst doing the 3 peaks. For basic hill walking I fully recommend. If your going to be fell running then you will need to buy the more expensive ones that have a breathable fabric like gore Tex.

Not great

Not overly waterproof. Got them yesterday and used them on the way home from work during which it was raining on and off. Got home and my trousers were wet underneath. used them for around 45 minutes

Additional Product informations


Main fabric

  • 100% Polyester


  • 100% Polyurethane

Waterproofing of the garment

This garment has been validated in a shower test under 60 litres of water/sqm/hour for 2 hours. This test reproduces the average conditions of a rain shower. The fabric of these overtrousers has water-repellent properties: it lets water slide over its surface without seeping in. 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. What's more, all the seams are taped.

How to ensure your overtrousers stay waterproof over time

In order to maintain good waterproofing over time, the fabric's water-repellent properties must be restored regularly. 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. If you are washing it, it must be thoroughly rinsed.

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.

Component breathability

To find out whether a fabric is breathable, we measure its thermal evaporative resistance coefficient (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

A score for comparing products' environmental impact

On a scale of A to E, this jacket obtained a score of B. Our products' environmental impacts 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

Our teams work to find innovative processes that reduce water consumption or water pollution during the production process. The "dope dying" (bulk dying) process saves up to 60% of water and significantly reduces the amount of CO2 emitted. This also reduces colour fading in the garment over time. As of 2019, we are now using this new procedure on these over-trousers.

How to choose your waterproof overtrousers based on your outings and level of exertion?

During a sporting activity, you perspires to varying degrees, depending on the intensity or length of the effort. If the fabric's breathability is not suited to the type of activity/exercise, your perspiration will condense inside the jacket. You feel damp inside: this isn't rain getting through, but condensation from sweat. You therefore need to choose over-trousers in line with your activity type. This product is designed for 2-hour hikes at no more than 5km/h.


Our hiking overtrousers are guaranteed for 2 years.Our commitment? To offer you long-lasting products that you can use on all your country hikes and walks. Because the products we love the most are those that have a story behind them... and plenty of life in them yet!
