Good quality product!

bought for winter trek, to test on site

Bigger size

On this product I would say that the color does not correspond to the image of the product and it is not a designation of ash blue. For me it is a nice compromise of a dark turquoise with a very pretty effect.

Lovely walking shirt for colder days

Great shirt, comfortable to wear, not itchy and nice and warm. Does not absorb odors. Can be combined with a wind stopper in case of strong wind. Will buy it again.


Very satisfied with my purchase. Light and warm, easy to maintain! I recommend

Perfect for winter

I used the T-shirt in the mountains at minus temperatures and even though it is thin, it was enough for climbing. Your back is always sweaty, but the shirt dries quickly and doesn't stink at all. I used it 5 times and it still didn't smell bad. I also have the impression that despite sweating, it keeps warm, unlike synthetics. I carry a heavy backpack and there are no signs of wear so far, I recommend it.

Super comfortable as a 1st or 2nd layer

I really like this very soft and not too tight t-shirt. Soft, comfortable and warm, I put it as a first layer and in very cold weather as a 2nd layer of 4 over a sports damarr. So glad it's flexible. The trucker collar is really a plus because it allows for ventilation when the effort causes the body temperature to rise a little. I'm going to buy a 2nd one

soft sweater

perfect for hiking lightweight, easy to wash and dry I recommend

I loved it

Used it as the first layer for snow hiking and it's brilliant.

icon-circle-checkmark verified purchase

The material is very pleasant. On the other hand, in terms of size, when trying on it's a little tight... but after use the textile becomes really large and no longer sticks to the body. So disappointed with the purchase.

Additional Product Information


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

How have we enhanced the durability of our t-shirts made with merino wool?

We have used a BETA-SPUN yarn structure in which the polyamide threads coat the Merino wool fibres. This protects them from rubbing and cuts without affecting their properties.

Odour control

The components used reduce bad odours. Laboratory tested according to ISO 17299-3This means you can carry less clothing when trekking!

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 Inchfreezing effect Inch is therefore reduced by the merino wool.

Do you have a final word of advice before using it?

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

How to wash your t-shirt made with merino wool?

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 Zip 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.
