Perfect for cold days, ice rinks

Very warm, very comfortable fit. Wearing for walks and to watch the kids play hockey in cold rinks. Keeps me warm always. Washes well on delicate, hang to dry.

Lovely top

I love this top. The colour is fab and it’s great for chucking on when there’s a chill in the air. I would say it’s slightly on the small side but I like something fitted.

Velmi pohodlná triko/mikina

Z merino výrobků z Decathlonu, které jsem zkusila, je tahle mikina asi nejlepší. Pěkně hřeje, i když je spíš tenká Oceňuji návleky na palec a hezkou barvu

Merino tričko se zipem

Výborně odvádí pot a zároveň nestudí. Používám jak na běžky, tak i na ferraty, velká spokojenost.

Perfektně odvádí pot a nestudí. I při delším nošení není cítit. Používám jako druhou vrstvu. Doporučuji zakoupit o číslo menší velikost než běžně nosíte.

Reducing 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.

How does wool reduce the proliferation of bad odors?

Wool from Merino sheep naturally controls the spread of bacteria that cause bad smells. It can therefore be worn several days in a row and means you can take less clothes when backpacking!

What are our commitments to animal welfare?

We only use wool from Merino sheep bred on farms in South Africa that do not practice mulesing. We decided to build a partnership with a group of breeders (Konsortium Merino) to guarantee respect for animal welfare and the environment. This gives us the full traceability we need to guarantee the origin of the wool.   More information:

How to wash your merino wool t-shirt

We recommend that you machine wash your Merino wool T-shirt at 86°F 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

The Trek 900 T-shirt was tested by 9 users in the Massif des Bauges in October 2019. These testers, who are independent of Decathlon, were supported by our design teams: Maïté, our product engineer, Mélanie, our designer, and myself, the product manager. For 5 days, we tested this T-shirt together in cold, snowy conditions, with some fine days of walking and a number of nights in a bed-and-breakfast or bivouac. We used this test to validate the product in use.
