The sleeved t-shirt…

The long-sleeved merino t-shirt, essential in summer and winter when hiking, Trekking... Protects from the cold, excessive heat and the sun. A wider range of colors, particularly in bright colors (useful for identification in the event of an accident) in the first layer would be welcome.

This is the first time I went hiking in this piece of clothing (in late March). I think it’s a good thing that I’m wearing this piece of clothing. It has a good effect of wicking away sweat and keeping warm. Although you still feel cold when the wind blows, you can just wear a jacket. improve.

Holds up well to machine washing and keeps its shape. Advantage the silhouette.

The best material

Very good merino tshirt. Used for 2 days of hiking in winter, the limitation of odors was very effective. Dried relatively quickly after getting caught in a rainstorm that even soaked through the Goretex jacket (I had to take my jacket off of course).

It's ok

the shirt itself looks good, adapts to the body, but stretches a bit after washing

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:

Product testing

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.
