Great product

I just bought it, so I can't comment on long-term use, but during the 5-day plateau camp, I slept in a -4 comfort rating sleeping bag, wearing only these underwear. According to my previous experiences, the comfort level of the overalls is +7 degrees maximum, provided that you are fully clothed. I spent 5 very comfortable nights with these underwear in the range of 3-7 degrees. Although we did not have the chance to take a shower in the plateau, I did not feel any odor or discomfort after 5 days. There is absolutely no stinging or itching sensation. It became even softer when I washed it before first use according to the instructions. I was very pleased, I recommend it.

Additional Product Information


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

Odour control

The component limits perspiration odours. This Merino wool t-shirt can therefore be worn several days in a row and means you can take less clothes when trekking making for a lighter backpack!

Reduction of the freezing effect

When you make a physical effort and sweat heavily, the merino wool easily traps the insulating warm air and can absorb up to 35% of its weight in moisture without making you feel damp, which is appreciable in cool weather. In hot, dry weather, the evaporation of the water in the wool absorbs energy, which cools the body slightly at the same time.

Tip before use

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 MT500 MERINO wool T-shirt at 30°C on a normal cycle, preferably with liquid detergent. Dry flat and NEVER tumble dry unless you want it to shrink by one or two sizes!For more information:

Product testing

In November 2018, 8 trekkers (4 men and 4 women) and part of the Forclaz design team tested this T-shirt for four days in the Southern French Alps (Lus La Croix Haute). You can expect wind, rain, a bit of snow, a bivouac... and a lot of fun! We were then able to make the final modifications and validate it for mountain trekking use.
