Worn as a base layer directly against the skin to maximise sweat evacuation.

Ideal under a lightweight windproof in changeable conditions.

The mountain spirit. The lightness of trail.

"French Montagnard" — it's more than a name. It's a mindset: authenticity, solidarity, humility.

The French Montagnard is the trail t-shirt that Cimalp runners have loved for years. It was designed for trail runners who want it all: the lightness of an ultra-light, the protection of long sleeves, and anti-odour performance for the long haul.

Because mountain people don't overthink it. They just go.

I'm 1.75 meters tall and weigh 75 kg, with a bit of a belly, and I opted for a trail running t-shirt in size M. I really appreciate the cut, which is very comfortable and flattering. The white color is very aesthetically pleasing, although it's slightly see-through at the bottom. I haven't yet had the chance to test the t-shirt when it's completely wet, so I can't say for sure how that affects the transparency. As for the fabric, it's extremely comfortable and pleasant to wear, which is essential for long trail runs. The lightness and breathability of the material are real assets, especially on hot summer days. Overall, I recommend this t-shirt without hesitation. It's an excellent choice for those looking for both style and comfort.

I usually wear a small, but I had to get a medium for it to fit! Perfect t-shirt, very light and breathable, dries very quickly and you forget you're even wearing it while running! I recommend it even for runs lasting several hours!

Meets our expectations. True to size (M for 173cm height, 99cm chest and 75kg), but fits looser than the t-shirt version. Don't be surprised when you try it on. More suitable for autumn and spring than winter.

A very nice and comfortable T-shirt, especially the long sleeves, designed for hiking in warm weather. Long-sleeved versions are more readily available for winter. But for hikers who have trouble with the sun, it's great to find this type of T-shirt.
