Men's waterproof over-trousers

I'm size M, bought size L, way, way, way too small for me. And no, it's not me being unrealistic about my size.

Do the job!

Wore these for 12 miles at the end of a winter ultra. Howling wind and rain kept at bay. Rolled up small enough in the bag for storage.

Incorrectly labelled

I am a 30" waist and have never worn anything labelled 32"W as they would be too big. These trousers are called overtrousers and should be big to take into account that they will be worn over your attire to avoid them getting wet. I ordered a 32"W-33"L that would be big enough to go over my clothes. When they arrived and tried on it was immediately obvious that they were too small and quite tight and clung to my legs, which would no doubt make my clothes wet in a shower of rain. I checked the label which said 32"W-33"L. I measured them and they were actually 26"Waist - 31"Leg. The elastic waist would actually stretch to fit my waist but would never go over clothes to fit properly. If you wish to order these then take this incorrect labelling into account. Mine were returned and a new ordered from elsewhere.

Additional Product informations


Main fabric

  • 100% Polyester


  • 100% Polyurethane

Water resistance of the fabric

The fabric of these over trousers is waterproof to 2,000 mmThis garment has been validated in a shower test under 60L of water/sqm/h for 2h This test reproduces the average conditions of a rain shower. The fabric is water-repellent: 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.We have taped 100% of the outer seams.

Fabric breathability

To find out whether a fabric is breathable, we test its total evaporative resistance (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

Our commitment to consume less water with this product

Textile dyeing requires a lot of water but also produces waste water from the dye baths. To reduce this environmental impact, we chose to use a bulk-dyeing process that incorporates the colour pigments from the yarn manufacturing phase onwards: a dyeing process called "Dope dyeing".This process is used on the blue colour (code 8732807).

Why choose recycled polyester?

By recycling plastic bottles or used fabrics to produce our polyester, we reduce the use of petrol-based resources while maintaining the material's quality and performance during your hikes.We used recycled polyester fibres for the black (code 8382416) colour.

Your health is our top priority

The fabric of this jacket is water repellent: 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. We have started to use a water repellent treatment without perfluorocarbons. Consequently, over the course of 2022, this model will be marketed with a water-repellent treatment that is more respectful of the environment

How to maintain the waterproof property of your over trousers over time?

To maintain a durable water-repellent fabric, we recommend reactivating it regularly.Do this every three washes (it is important to rinse abundantly) or after a dozen uses in the rain.You can easily reactivate the water repellent property by warming the fabric:- in a tumble dryer for 15 minutes (synthetic program) - with a hair dryer at a distance of 20 cm by going back and forth twice- or two passes with an iron on the delicate setting without the steam function.

Choosing your waterproof overtrousers according to your level of physical effort

During sports activity, the extent to which we perspire depends on the intensity or the duration of the physical effort If the fabric's breathability isn't suited to the type of activity/exercise your perspiration will condense inside jacket. You will feel damp inside this is not rain coming through but perspiration vapour condensing 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.

Recommended additional product

To protect the lower part of your body as well, and have a very efficient full protective outfit against the wind and rain showers, we recommend men’s Raincut 1/2 zip or full zip jackets. These jackets are also eco-designed (depending on the colours, they are dope dyed to reduce water consumption or made from recycled fibre).
