Is this trouser warm enough to wear on its own?

This model is designed to provide good thermal insulation during your winter outings. However, in very cold conditions or for more static activities, we recommend adding a base layer underneath to ensure optimal comfort.

Does this trouser protect against rain?

This trouser is water-repellent and windproof: it sheds water and snow from its surface. It will protect you during moderate showers. However, it is not a replacement for fully waterproof overtrousers in heavy, sustained rain.

What are the delivery times for this product?

If you place your order before 1 pm (excluding weekends), it will be dispatched the same day. Allow 2 to 4 working days for home delivery or collection point delivery within mainland France.

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 the hikers and mountaineers who tackle sustained elevation gain on technical trails, scree and glaciers.

Trousers built for those who alternate between multi-day trek self-supported and mountaineering routes on mixed terrain, without changing kit.

This type of user demands trousers that follow every movement on steep ascents, withstand repeated contact with rock and stays comfortable from dawn to bivvy.

How should you wear it?

Thanks to its half-elasticated waist and adjustable leg openings, it pairs perfectly with hiking shoes or approach shoes.

What makes the difference?

Its CIMAFLEX® technology, combined with Cordura® reinforcements on critical areas, delivers total freedom of movement without fear of premature wear. Its durable water-repellent treatment effectively protects against external moisture.

Move without constraint on every terrain

In the mountains, trousers take a beating. Steep ascents, technical descents, repeated friction against rock. Rigid gear ends up limiting range of motion, wearing down your footing and giving way at critical points.

These trousers were designed to follow every movement, not restrict it. Their stretch construction adapts to every foothold on ascents and traverses. Strategic reinforcements absorb repeated impacts without weighing down your progress. They stay supple under effort, durable over time.

Because in the mountains, moving freely changes everything. And durability must last as long as your commitment.

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.
