Technical information


We only use wool from merino sheep bred on farms in South Africa that do not practise mulesing.
We decided to build a partnership with a group of breeders (Konsortium Merino) to guarantee respect for animal welfare and the environment.
This means we have full traceability, which allows us to guarantee the origin of the wool.

Odour control

The components used reduce bad odours. Laboratory tested according to ISO 17299-3
This means you can carry less clothing when trekking!

Sizing and fit

This T-shirt has a fitted cut for enhanced moisture transfer to the outside of the fabric.

Select your usual size or one size larger if you prefer a looser fit.

Reduction of the freezing effect

After any physical effort that involves a lot of perspiration, wool helps to preserve the body temperature while synthetic fabrics cause the temperature to drop faster.
The unpleasant cooling or "freezing effect" is therefore reduced by the merino wool.

Do you have a final word of advice before using it?

For a softer feel, wash your t-shirt before first use.


We recommend that you machine wash your Merino wool t-shirt at 30° on a normal cycle, preferably with liquid detergent.

Dry flat. NEVER tumble dry unless you want to end up with a Merino T-shirt fit only for a doll!

Product concept & technology

Product Composition

Main fabric 100% Wool


We've tested the material in a climate-controlled chamber in order to determine its performance level. The results highlighted the heat-regulation properties of wool. Indeed, after making a physical effort and sweating a lot, wool helps to maintain a consistent body temperature while synthetic fabrics cool down faster.
The unpleasant cooling or "freezing effect" is therefore reduced by the merino wool.

Approved By

Our team of designers is based at the foot of Mont Blanc, in the Haute-Savoie region (France).
