In summary This content is written by AI

Customers love its lightness, flexibility and outstanding comfort: several describe it as a genuine “second skin” that feels pleasant during training. They also appreciate its breathability and quick-drying fabric, with one customer specifically noting that it does not retain sweat odours. Warm enough for winter running while remaining lightweight, it suits mid-season outings, hiking and outdoor activities. Its fit is considered well adjusted, and several customers also wear it outside sport or have already bought another one.

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!

Frequently asked questions

Choose your usual size: this t-shirt fits true to size. If in doubt, the size guide on the product page gives the height in cm and body weight for each size.

Yes, this packable t-shirt folds into its side pocket, so you can carry it in a bag after taking it off.

Yes, it’s a t-shirt for every season. Wear it on its own in warmer weather: it stays breathable and dries quickly. When it’s cool, wear it as a base layer under a gilet or lightweight windproof jacket.

Yes, with care. Its fine-knit fabric is more delicate than a heavier fabric: repeated rubbing from backpack straps or a hip belt may leave marks. For heavy loads, choose a thicker t-shirt.

Yes: the fabric is rated UPF 30, and the long sleeves cover your arms.

Our CIMAFRESH technology is an antibacterial treatment that limits odours during activity and is designed to remain effective after several washes. It reduces odours but does not eliminate them.

The main fabric is 100% recycled polyester; the ribbed trims are 100% polyester. This is a synthetic t-shirt: the traceability information notes that washing releases plastic microfibres.
