The t-shirt you won't even feel in warm weather.

On a sun-exposed trail, fabric that sticks to your skin can quickly spoil an outing. This t-shirt takes a different approach: an ultra-fine, micro-striped knit that lets air through and moves with you.

Lightweight does not mean unprotected. Its treatment limits odours during long days in the mountains, while the knit provides sun protection on exposed routes.

Because in hot weather, the best kit is the kit you no longer notice.

Key features

Very quick drying

Active moisture wicking: sweat is continuously drawn away, and the fabric dries very quickly.

Long-lasting anti-odour

Built-in antibacterial treatment: limits odours during long days in the mountains.

Ultra-lightweight fabric

Ultra-light at 80g in size M: you barely notice it against your skin.

CIMAFRESH Technology

durable freshness and odour reduction during activity.

  • Antibacterial action : limits the growth of bacteria responsible for unpleasant odours.
  • Long-lasting freshness : allows the garment to be worn longer without any feeling of discomfort.
  • Lasting comfort: treatment* discreet, odourless, without affecting the breathability or feel of the fabric.

CIMAFRESH technology is designed to maintain its effectiveness over time, even after multiple washes, contributing to more durable garment use.

*Antibacterial treatment based on silver chloride (biocidal product).

In summary This content is written by AI

Customers love its lightness, comfort and pleasant fabric, making it feel almost weightless even during intense indoor workouts and heavy sweating. Many also appreciate its breathability and very fast drying: it stays fresh on hot days and dries quickly after heavy perspiration, including during hiking in Réunion. Several customers use it happily for trail running, running, trekking or fitness. One thing to bear in mind: the very thin fabric can be fragile with a backpack whose back panel is abrasive, so take care of it.

I'm a devoted Cimalp fan. This t-shirt ticks all the boxes for trekking. Comfortable, very light in the backpack, and dries super fast. I love the feel of the fabric. I bought one in L and another color in XL, and everything fits perfectly.

Lightness promise perfectly delivered. I also wear it in the gym where I appreciate how it feels like I'm wearing almost nothing, even when sweating heavily.

It’s incredible. Whether running or trail running, I’ve never been soaked. It dries quickly and wicks sweat really well. Super lightweight and durable. Used in very hot weather. I highly recommend it.

Great hiking t-shirt. Used in Réunion, dries very quickly despite heavy sweating with the backpack. No uncomfortable feeling. No odors. Be careful about durability though: the back is very thin, and an aggressive backpack can damage it quickly.
