Which size should I choose?

Choose your usual size: this t-shirt fits true to size. It has a close fit, so if you’re unsure, check the size guide on the product page. It lists the height in cm and body weight for each size.

How should I care for them?

Wash at 30 °C maximum without fabric softener and leave to air dry: it dries quickly, so avoid tumble drying.

Does it pack into its own pocket?

Yes. This packable t-shirt folds into its side pocket, so you can carry it in your bag as a spare t-shirt.

Can I wear it under a backpack?

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.

Does it retain odours?

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.

Does it protect against the sun?

Yes, on the areas it covers: the fabric is rated UPF 30.

What is it made from?

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.

Garment assembly, weaving or knitting, and dyeing take place in China.

What are the delivery times for this product?

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.

Can I return the item if the size doesn't fit?

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.

The lightweight top that moves with your stride

It’s still cool at the start; on the climb, the heat builds and every gram counts. The right top is one you barely notice: it lets air through and moves with your stride.

Its fine, airy knit wicks away sweat, an antibacterial treatment helps limit odours, and reflective details improve visibility on night outings. Folded into its side pocket, it fits in your pack as a spare t-shirt.

The mountain spirit comes down to three words: authenticity, solidarity, humility. Because mountaineers don’t overthink it. They set off.
