Why choose 3-layer overtrousers?

3-layer overtrousers are tougher and offer more protection than 2-layer or 2.5-layer versions. These use our ULTRASHELL® technology.

What are overtrousers for?

Wear them over your trousers for protection from rain and wind, then pack them away when the skies clear. These are made for hiking, mountaineering and ski touring.

Which size should I choose?

They fit true to size, so choose your usual size. If wearing them over thick trousers, size up for more room around the thighs.

How many pockets does it have?

A waterproof zipped thigh pocket, large enough for a phone.

Does it withstand contact with crampons and ski edges?

Reinforcement at the lower leg protects the fabric from crampons and ski edges.

How much do they weigh, and how do you pack them?

They weigh 360g in size M. They pack down small and slip into your rucksack between showers.

How should I care for them?

Machine wash at 30 °C with zips closed, using a detergent for technical clothing and a gentle spin cycle. Do not use fabric softener. To restore water repellency, apply a reproofing spray after washing.

What are the delivery times for this product?

All orders placed by midnight are prepared the next day. In France, orders placed before 1 pm (excluding weekends) with Chronopost 24h are dispatched the same day. Delivery then depends on the carrier and takes 1 to 4 days in France. Delivery times for Europe and the rest of the world vary by destination.

Can I return the item if the size doesn't fit?

Yes, absolutely. You have 30 days to return it and get a refund or an exchange. Return shipping is free. The item must be new, unworn, unwashed, and have its original tag.

Who did we design it for?

For mountaineers, hikers and skiers hiking in the high mountains, where the weather can change quickly: protection that goes on fast and adds hardly any weight to your pack.

What makes it different?

Our ULTRASHELL® technology: a three-layer membrane, waterproof to 20'000 mm and breathable at 80'000 g/m²/24h, for lightweight overtrousers that pack down into the bottom of your rucksack.

How waterproof is it?

A 20'000 mm Schmerber rating and sealed seams protect against rain and snow. They also block strong winds of 60 to 90 km/h.

How breathable is it?

The fabric releases moisture vapour at 80'000 g/m²/24h, while side zips ventilate your legs. At high intensity, any waterproof trousers will retain some moisture.

Overtrousers you can pull on without a second thought

Clouds close in above the mountain pass. The wind picks up, the first drops fall, and you're still a long way from the end of your outing. Sitting down to change isn't an option: neither your pace nor the group can wait.

Both zips open from the waist to the hem, so you can pull the overtrousers on over your trousers and shoes without taking anything off. They adjust at the waist and ankles, have taped seams, and their membrane lets heat from exertion escape while keeping rain out.

Lightweight, they pack down and go back into the bottom of your rucksack as soon as the sky clears.

Because in the mountains, the best protection is the gear you reach for without hesitation.

Key features

Full-length double zip

- A zip on each side runs from the waist to the hem, so you can put them on and take them off without removing your footwear.

Waterproof zipped pocket

- A zipped thigh pocket, large enough for a phone, protects it from the rain.

Adjustable waistband

- Elastic at the back and two hook-and-loop tabs at the sides adjust the waist fit.

Adjustable leg hem

- Press studs and a drawcord adjust the leg hem around the ankle, while a reinforced panel protects it from crampons and ski edges.

ULTRASHELL® Technology

Waterproof and breathable protection to tackle demanding mountain conditions.

High waterproofing: high-performance membrane combined with constructions adapted to wet and windy environments.
Optimised breathability: microporous membrane promoting moisture evacuation during exertion.
Windproof protection: limits heat loss and improves comfort in exposed conditions.

Designed for intensive use in the mountains, ULTRASHELL® technology favours built-to-last constructions to ensure a high durability and reliable long-term protection.

In summary This content is written by AI

Customers appreciate the excellent build quality, neat finish and thoughtful design, with waist and ankle adjustments and side zips that make it easy to pull on, even over shoes. Several tested it in heavy or torrential rain for up to two hours and found it highly protective against rain and wind while allowing free movement. Some also found it warm without causing perspiration. It can feel tight around the thighs or over trousers, so choose one size up; one customer also reported water getting through the knee zip. Well suited to cycling, hiking and mountain use.

One size larger than my usual size for use on a bike and greater comfort when walking. I tested this product on its very first outing in torrential rain, and it performed perfectly. It also provides excellent wind protection.

High-quality product, very effective and breathable despite a day of rain; the size fits well (size M, 1.80m, 71kg). Highly recommended.

Very fast shipping, perfect size, tested this weekend in the rain: Perfect, allows for freedom of movement, very good waterproofing. Otherwise, the only downside to this gear is that it's very high quality, so there's little chance of buying it again (HUMOR).

Overall, these overpants are true to size (inseam and waist measurement). The finishing is excellent, and the fabric is high quality. For me, the problem with pants is often the available leg opening. Size M was perfect at the waist but a little tight around the thighs, so I opted for size L, which still fits well at the waist and allows more room for pants, even slightly thicker ones. This way, I can wear them in both summer and winter.

Recently used in October 2026 on a trek along the GR 65 where I encountered several heavy downpours and drizzle. I find the breathability and waterproofing to be excellent.
