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 mountaineers, ski tourers and ice climbers who practise intense winter activities in exposed terrain.

Designed for those who move a lot and in all positions — the straps keep the trousers from slipping down, and the mesh openings manage heat during effort.

Those who don't want to choose between protection and ventilation.

How should you wear it?

Worn as a main layer for mountaineering, ski touring and ice climbing. Activate the braces for technical sections and long ascents. Open the side vents on the way up. Regular fit — order your usual size.

What makes the difference?

Its adjustable shoulder straps and back rise keep the trousers in place across all technical mountaineering positions — no slipping, no gap at the lower back.

The softshell that stays put

In mountaineering, in a high cross position or on the ascent, a trouser without braces will constantly slip down. The back rise opens up. The cold gets in.

This 3-layer softshell stays in place thanks to its Velcro braces and back rise. Its 2 large mesh openings vent heat without letting wind in. The edge guard reinforcements withstand technical terrain.

Protection maintained. Comfort even in tough conditions.

In summary This content is written by AI

Customers appreciate this functional, comfortable, high-quality pair of trousers, with materials and zips they describe as impeccable. They particularly praise its effective protection against cold and wind, along with the large side openings, which are especially useful for releasing heat during ski touring. The reinforcements are well placed, and several customers also use it for hiking, snowshoeing or in Lapland. Do bear in mind that the fit can be either too tight or too loose depending on body shape, the braces sometimes lack adjustment, and the pockets are considered too shallow.

Size fits very well. I'm a 179cm man. I was expecting a tad warmer pants, they do feel a bit cool in -4C, but still comfortable in that temperature. I will put these into real test in -20C in Finnish Lappland and we shall see.

I wore these pants for a week in the snowy mountains with temperatures around -5/-10°C and I wasn't cold for a single moment... They offer top-notch comfort and protection. I'm 1.65m tall and weigh 64.5kg, and size S fits me perfectly.

I weigh 73 kg and am 1.75 m tall. These are great pants, well-cut and close-fitting. The fabric is supple and soft to the touch, and the comfortable lining should provide excellent warmth in very cold weather. The leg length is perfect for me. Based on online reviews, improvements have been made to the gaiters, which now fit perfectly over my hiking boots, and the side ventilation openings now have mesh protection to prevent snow from getting in, which wasn't the case in previous versions. For me, the suspenders are a plus compared to a belt because the pants come up high in the back. However, the Velcro closures on the suspenders could be placed higher for those with a smaller torso than usual, which is my case. But this is a minor drawback considering the quality of the product. I'm going to use them for snowshoeing, cross-country skiing, and hiking. I recommend this product.

Very comfortable pants that fit perfectly. Ideal for skiing and snowshoeing, and I've already tested them! The pants seem very robust and well-made. At 188 cm tall and 85 kg, size XL is the right choice.

Very comfortable trousers for walking, light and flexible. I use them regularly for brisk walking, in temperatures between 0° and 3°C. They feel cool at first, then the body warms up comfortably afterwards. The suspenders are practical for good support. Order your normal size (size 42 for 1.75m and 78kg).
