Who did we design it for?

For hikers, trail runners and climbers who move between disciplines without changing kit, from technical trails to fast descents.

What is the fit?

Straight, close-fitting cut: take your usual size. Only one leg length is available; there is no short version.

How comfortable is it?

Ultra-lightweight and stretchy, with an adjustable elasticated waistband. Reviews describe it as light and comfortable to wear; a few customers find it snug around the calves.

What makes it different?

Our CIMAFLEX technology: stretch fabric that moves with every bend, with articulated, pre-shaped knees and Kevlar® reinforcements at the lower legs.

The trousers that don’t pull on the climbs

Steep climbs, bursts of speed on singletrack, quick transitions between disciplines. Every stride puts the fabric to work; every bend tests the cut. Trousers that pull or cling break your rhythm.

These trousers are designed to go unnoticed when you’re pushing hard. Their stretch construction moves with you without restricting your knees. They keep you moving smoothly on technical terrain and easy-going paths alike.

Because in the mountains and on the trail, the best kit is the kit you forget you’re wearing. And performance starts with freedom of movement.

In summary This content is written by AI

Customers appreciate its very light weight and comfort, even in warm weather: the stretch fabric moves with you on steep climbs and stays breathable without feeling hot, while providing a windproof effect. Several have worn it for hiking, including one customer on the 1,000 km Camino del Norte, as well as for paragliding, bikepacking and gravel riding. The finish and practical zips are also praised. Be aware, however, that the cut is very close-fitting and sizing can be inconsistent: check your measurements carefully; the pockets are a little small for a large smartphone.

Having purchased other products in the past didn't hesitate when looking to acquire trousers for Nordic Walking/light weight hiking and these fit the bill perfectly. 1m 80cm tall and the M sizing was also fine. Usual no problems with ordering or delivery. Sure to be back again in the future as tried and tested.

Great cycling pants, comfortable and well-cut. I wore them while bikepacking with seamless tights for a super experience. The fabric is nice and stretchy and breathable, perfect for pedaling – you barely feel them.

FAQ

Frequently asked questions

Choose your usual size: these trousers fit true to size. They have a straight cut that sits close to the body. The size guide on the product page lists the height in centimetres and corresponding weight for each size.

They weigh 310g in size M. These ultra-lightweight trousers are designed to feel barely there during exercise.

It depends on the phone. The zipped back pocket is designed for a phone and small items, but the other pockets are narrow: a large smartphone will be a tight fit.

Silicone strips keep the leg cuffs in place over your shoes, while reinforcements protect them from abrasion caused by stones and vegetation. They fit snugly at the ankle and have a zip to make them easier to pull on.

No, it is water-repellent: the DWR treatment sheds raindrops during a brief shower, but it cannot replace waterproof trousers when the rain persists. It also protects against sustained winds of 40 to 60 km/h.

Wash them at 30 °C maximum without fabric conditioner, then air-dry them: avoid tumble-drying. The fabric is made from polyester and elastane, a synthetic material that releases plastic microfibres into the environment during washing.

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.

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.
