Technical Information

What is our commitment to animal welfare?
We only use wool from merino sheep bred on farms in South Africa that do not practise mulesing. We decided to build a partnership with a group of breeders (Konsortium Merino) to guarantee respect for animal welfare and the environment. This means we have full traceability, which allows us to guarantee the origin of the wool. More information: visit our website
How did we improve the durability of our T-shirts containing merino wool?
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.
Odour control
Wool from Merino sheep helps prevent unpleasant 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
After exercise and sweating heavily, Merino wool prevents evaporation helping to maintain body temperature by absorbing the majority of the body's moisture. This therefore reduces any unpleasant chilling effect. Conversely, a synthetic material lets the body temperature go back down again faster.
Tip before use
For a softer feel, wash your t-shirt before first use.
How to wash your merino wool T-shirt?
We recommend that you machine wash your MT500 MERINO ZIP T-shirt at 30° 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 test
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.
