Super comfortable, well cut, but messy

I love it but after first use, a stain, and it didn't come out in the washing machine. I wear it to go to work by bike without having to change all day. Great in terms of smells, comfort, but the stain is a stain :( Being in black is sad in the end....

Additional Product Information


Main fabric: 100.0% Wool

What are our commitments in favour of animal welfare?

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. More information: visit our website

Odour control

The components used reduce bad odours. Laboratory tested according to ISO 17299-3This 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

When you make a physical effort and sweat heavily, the merino wool easily traps the insulating warm air and can absorb up to 35% of its weight in moisture without making you feel damp, which is appreciable in cool weather. In hot, dry weather, the evaporation of the water in the wool absorbs energy, which cools the body slightly at the same time.

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

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

How to wash your t-shirt made with merino wool?

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!For more information:

Product testing

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.
