Very good value for money.…

Very good value for money. Keeps you warm. Don't sweat and very comfortable to wear.

Very good dry product…

Very good product dries quickly and keeps you warm but not too warm (not enough for a real thermal layer if it's very cold). Too bad there aren't better colors.

Long sleeve hiking t-shirt

Very good cut and color, keeps warm in 1st layer, no smell of perspiration, does not crease when washing by hand and does not deform in the wool program machine. Very satisfying, I plan to take the t-shirt for the summer.

Too long

This sweater is too long for me - it would be better if it was 10 cm shorter. Currently it is too long for action sports.

I recommend, great for hiking, pleasant material

I really like this blouse. The color is very nice, as is the cut. It is comfortable, pleasant to the touch, does not retain sweat or odors. For now, I only wore it in winter and spring. It is resistant to abrasion, I wore a backpack on the back and it did not peel off.

Used when hiking…

Used when hiking with a backpack, which generates perspiration even in cool weather. The T-shirt absorbs without problem, and does not create a cold effect like cotton. Worn alone under a breathable windbreaker there is no heatstroke either. Also worn under a sweater this winter, it's very pleasant.

To wear both in summer and in winter!

I use this top for my winter hikes, as a first layer, or as a single layer for my summer hikes in the mountains! Merino wool wicks away perspiration very well, it allows me to stay dry even in hot weather, and provides a little warmth as an underlayer in winter. The material is very soft and does not itch, in addition to being anti-odor, which allows you to wear it for several days in a row without worries during treks!

Really disappointed by its resistance. Washed 1-2 times a week for 3 months and it's already pilling.

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.
