Pleasant on the body, you can easily feel it when sweating.

This wasn't what I expected

I am disappointed. While the material itself is pleasant, the color of the T-shirt on the website is completely inconsistent with the color in real life. On the website it is beige, in real life it is faded yellow. Much uglier than in the photo. Additionally, I ordered a size larger than I normally wear and the T-shirt was very tight. The photos on the model do not suggest this.

Don't limit odors so much...

I bought this T-shirt because I literally "snapped" my synthetic T-shirts because of the smell of sweat. Well, I'm rather disappointed because the T-shirts remain stained under the armpits and the smell doesn't go away, despite several washes, white vinegar, etc. ...Sorry, but for this criterion, I advise against it.

Quality in sharp decline

I have been using a copy purchased in the summer of 2022 for 2 years and it has barely moved, the quality is really great. I bought the same model 2 months ago and the quality is no longer the same at all, it is smaller in size and generally speaking, the lengths have been shortened, all this for €5 more than before. 'era. I am rarely disappointed by Decathlon, but I rather recommend the same one in red or blue which seem to have not suffered any budget cuts. Happy hiking everyone!

Ideal under layer

This jersey is great as a base layer, I wear it under a sweater every day or a fleece when hiking. I sometimes when it's hot and I take off a layer to wear it alone. Be careful in this case it is very slightly transparent The 100% merino component really limits odors and I can easily wear it 3 - 5 days in a row by airing it out in the evening Soft and comfortable to wear, we can only blame it for its finish a little weak on the overlocks and seams (which suggests a slightly diminished durability) The thickness is perfect in mid-season, a little thin for winter for my taste

I recommend

Very comfortable T-shirt, but definitely too expensive for me. nevertheless, it is so comfortable that this is my second one.

Quality declining.

Pleasant t-shirt to wear but much thinner than a previous model, purchased a few years ago. Very transparent, thin like cigarette paper, probably worn out in a few weeks. And the ecru color is actually a stunning pale yellow.

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) in order to guarantee animal well-being. This also offers full traceability, meaning we can guarantee the origin of the wool. More information: visit our website

Odour control

The component limits perspiration odours. This Merino wool t-shirt can therefore be worn several days in a row and means you can take less clothes when trekking making for a lighter backpack!

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. Conversely, a synthetic material lets the body temperature go back down again faster.

Tip before use

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

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.
