Product Customer Reviews
I use it for running when I'm on the move and don't want to carry too much weight. This shirt is very comfortable to wear and the anti-odor properties allow you to wear it multiple times without washing and without odor.
Very breathable, comfortable to wear. A bit fragile, I put it on a stake at the collar and it started to open. Maybe my fault!
Perfect
too little moisture regulation
Excellent
A classic merino with a good fit.
The price to quality ratio is unbeatable. Awesome.
A product that I really like. I am switching to all Merino because, whatever people say, synthetic t-shirts end up having bad smells, which is not the case with Merino wool. For resistance to wear, the mesh areas scared me but they seem quite resistant. I will see with use
cute, cheap and thermo-regulating
Initially, I wanted to take the MT900 but unfortunately it only comes in one color that was too flashy for me (bright orange). So I went to the range below, the MT500, which comes in several colors. A nice surprise because honestly, the t-shirt does the job well, especially in terms of friction and breathability.
Fitted cut (or take a larger size). Merino wool makes up 89% of the main part of the shirt, the rest is polyamide. Despite this, the shirt is of very high quality, functional, dries quickly and does not smell (tested on a hike in India) and serves its purpose. It can be used very reliably for layering. Like all Merino clothing, it is not very abrasion-resistant, but this shirt behaves much better than 100% merino. For me, a great price-performance ratio.
very comfortable, I recommend!
The length of the clothes is long, comfortable to wear, and not easy to absorb odor
The length of the clothes is a bit long, it is comfortable to wear and not prickly, and the ventilation design on the back is very cool
Very pleasant product to wear on the skin…merino brings real comfort in winter. The only downside is that it remains quite fragile, holes appear quickly…it is an item for calm sports such as walking. It is also a comfort for everyday life

Additional Product Information
Composition
Main fabric: 89.0% Wool, 11.0% Polyamide ; Yoke: 66.0% Wool, 24.0% Polyamide, 10.0% Elastane
How does the mt500 merino t-shirt limit odours?
The components used reduce bad odours. Laboratory tested to standard ISO 17299-3. Main fabric: 89% Merino woolMesh panels and a mesh fabric under the arms and in the middle of the back: 66% Merino wool, 24% Polyamide, 10% Elastane.
How does the mt500 merino wool t-shirt help perspiration evaporate?
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.
What is the fit of the mt500 merino wool t-shirt?
This T-shirt has a slightly fitted sports cut to help wick away moisture to the outside of the fabric. Select your usual size, or one size larger if you prefer to wear your T-shirts looser.
Where does the merino wool used for the mt500 merino wool t-shirt come from?
We 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 traceability, meaning we can guarantee the origin of the wool.
A tip before using the mt500 trekking t-shirt?
For a softer feel, wash your t-shirt before first use.
How do i wash my mt500 merino wool trekking t-shirt?
We recommend you machine wash your Merino wool T-shirt at 86°F on a normal cycle with Merino wool liquid detergent sold under code 8817234. Dry flat and NEVER tumble dry unless you want it to shrink by one or two sizes! You can find an article on looking after merino wool clothing on the Forclaz website.
