Pleasant material, color suitable for the forest.

Very good product for walking and also a very good look that can be worn every day.
Super warm and comfortable to wear
good
T-shirt served me in troubleshooting as pajamas in the high mountains under tent canvas
excellent product; I took it a little large, just a matter of taste... Solid if you take care of it. To sleep in a bivouac!
Can you buy
Did welll for machu pictures and skiing
Merino wool has really become my favorite material for hiking, it's warm when it's cold and breathable when it's hot. This t-shirt does not retain odors even after exercise. On the other hand, you have to be careful with maintenance because this material remains a little fragile.
Good fit. Value for money!
Excellent product for base layer. Marino wool helps reduce odour.

Additional Product Information
Composition
Main fabric: 86.0% Wool, 14.0% Polyamide ; Yoke: 98.0% Wool, 2.0% Polyamide
How have we reinforced the durability of our merino wool t-shirt?
We use a BETA-SPUN yarn structure in which the polyamide threads coat the Merino wool fibers and protect them from rubbing and cuts without affecting their properties.
Odor control
Wool from Merino sheep naturally controls the spread of bacteria that cause bad odors. This Merino wool T-shirt can therefore be wornseveral days in a row and means you can take less clothes when backpacking 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 quicker.
Tip before use
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 86°F on a normal cycle, preferably with liquid detergent. Dry flat and NEVER tumble dry unless you want it to shrink by 1 or 2 sizes!For more information: https://www.forclaz.fr/conseils/comment-laver-mon-tee-shirt-de-trek-en-laine-merinos-tp_1550
Product testing
In November 2018, 8 trekkers (4 men and 4 women) and part of the Forclaz design team, tested this T-shirt for 4 days in the southern French Alps (Lus La Croix Haute). On the agenda, 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 use for mountain backpacking.
