MERINO T-shirt

Pleasant to wear the warmth is there but I thought it would be more important nice look and I like this color

I didn't keep it

I didn't keep this t-shirt at first because L was too big and M was unavailable. But, when trying it on, I moderately liked the feel of the fabric, the cut, this unpleasant cross seam. So I wouldn't have ordered the M in exchange if it had been available. I preferred another model. Concerning warmth, sweat management and resistance to friction, I cannot evaluate these criteria only after fitting.

Can be worn inside or outside

Additional Product Information


Main fabric: 86.0% Wool, 14.0% Polyamide ; Yoke: 98.0% Wool, 2.0% Polyamide

How did we improve the durability of our t-shirt?

We use a BETA-SPUN yarn structure, i.e. the merino wool fibres are coated with a fine sheath of polyamide filaments to protect them from rubbing and cuts, without affecting the properties of the wool.

How does the wool reduce odours from perspiration?

The component limits perspiration odours. Laboratory tested according to ISO 17299-3This merino wool T-shirt can be worn for several days at a time, allowing you to carry less clothing on your trek and thus lighten your backpack!

Reducing the ”freezing effect”

Thanks to its structure, wool can absorb up to 35% of its weight in moisture without giving the feeling of being damp.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 do i wash my merino wool t-shirt?

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:

The Trek 500 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.
