Which size should I choose?

Choose your usual size. The size guide on the product page gives the corresponding height and body weight for each size.

Is there a short-leg version?

Yes: a short-leg version is available for men under 172 cm tall. No hemming needed.

No: they are water-repellent, not waterproof. A moderate shower will bead on the surface, but they cannot replace overtrousers in heavy, continuous rain.

How many pockets does it have?

Five: two zipped side pockets, one zipped rear pocket and two thigh pockets with hook-and-loop flaps.

How do I adjust the waist and leg openings?

The waistband is partly elasticated and has belt loops; no belt is included. A drawcord with a cord lock tightens each leg opening over a hiking or approach shoe.

Do they withstand brambles and contact with rock?

Cordura® panels protect the knees, seat and lower legs from rubbing against rock. Avoid brambles and very rough terrain: the fabric and reinforcements can be damaged.

How should I care for them?

Wash without fabric softener, which can clog the water-repellent treatment, and follow the care label. When water no longer beads on the surface, restore the water repellency with a suitable reproofing product.

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 hikers and mountaineers moving between multi-day treks and routes over mixed terrain, from technical trails to scree slopes, without changing trousers.

How warm is it?

Warm without being too hot: ideal for hiking from the shoulder seasons through winter. In severe cold or when stationary, wear a thermal base layer underneath.

How well does it protect against wind and rain?

They block sustained winds of 40 to 60 km/h and shed snow and water droplets thanks to a water-repellent treatment. Not waterproof: wear overtrousers in continuous rain.

What makes it different?

Our CIMAFLEX technology: a stretch fabric that moves with every step, with Cordura® panels at the knees, seat and lower legs.

Mountaineering

Move without constraint on every terrain

In the mountains, trousers work as hard as your legs. Steep climbs, technical descents, repeated contact with rock: stiff gear restricts movement, makes each step harder and wears out at critical points.

These trousers are designed to follow every movement, not restrict it. Their stretch construction moves with you on climbs and traverses. Reinforcements protect high-wear areas without weighing you down, while the water-repellent treatment sheds water droplets and snow.

They are suited to autumn and winter hikes, multi-day treks and mountaineering routes over mixed terrain.

Because in the mountains, freedom of movement makes all the difference.

In summary This content is written by AI

Customers love its comfort, balanced cut and the freedom of movement it provides every day. Many appreciate a fit that is neither slim nor too loose, as well as its softness and pleasant feel. They also praise its quality and sturdiness: several have bought another one or replaced an older model from the same range. It keeps you warm without overheating and performs well for hiking in cold or autumn conditions. A particularly suitable choice for outdoor outings.

Great hiking pants for fall/winter! Completely waterproof, lightweight, and flexible. They fit me perfectly, and shipping was very fast. Very happy with my purchase; I recommend this product. Info: I am 1.85m tall and weigh 80kg. I bought size M.

For someone 1.74m tall and weighing 78kg, the M fits well, but it's not suitable for those who want to gain too much weight... Note that the fabric is great, with just the right amount of stretch; good quality and a good cut.

I'd already tried the short Laos pants, which are great, and I'm not disappointed with the classic Laos. I find these pants just perfect! They're lightweight, warm, durable, breathable, and quick-drying. Lots of pockets, really great :-)

Durable and ideal pants for long winter or spring hikes. A bit too warm for summer.

Excellent product, exactly what I expected. I was able to test its waterproofness and windproofness during a recent hike in Iceland. Lightweight, warm, and very abrasion-resistant. The thigh pockets seem more for aesthetics than practicality.
