The t-shirt that covers your arms between seasons

In spring and autumn, the weather makes it hard to choose between short and long sleeves. This t-shirt settles it: it covers your arms without weighing you down.

Its fine, airy knit lets air circulate even under the sleeves. An antibacterial treatment helps limit odours, while reflective details improve visibility on night runs. Take it off along the way, and it folds into its side pocket to carry in your pack.

The mountain spirit comes down to three words: authenticity, solidarity and humility. Mountain people don't overthink it. They head out.

In summary This content is written by AI

Customers especially appreciate its very pleasant, lightweight and comfortable fabric, with a second-skin feel: many find it easy to wear for hiking as well as trail running. Lightweight, it is barely noticeable and dries quickly; several use it as an ideal mid-season layer, especially in spring, and one customer found it perfect for a marathon at 10–12°C. Fit and sizing can vary depending on your build, so check the look you want: some find it small, while others consider it too loose or the sleeves too long.

I've had this T-shirt for 2 years. I bought another one because it's so practical. Lightweight, breathable, with a nice design. It takes up barely any space when folded, so it comes with me on hikes and trips.

Excellent, breathable, keeps you warm. A bit large for me, maybe size M would have been enough.
