This was worth every penny it works brilliant bin on long hikes in the sun it felt nice and cool plus it wicks really good and no smell even after a few long hiking days would recommend
A workhorse of a baselayer, no donwsides really :)
Anything with merino wool goes up a star immediately! Warm, comfortable and fits lovely
Had it for a good few weeks now and I'm made up with it done a good few days out not had any problems I didn't even need to wash it after a good few walks didn't stink felt very comfortable so I think it's worth the money
Nice lightweight second level base layer. I wear it on top of a short sleeve layer. Great for slipping on to stop cooling after a gym session. Also great as part of a layering system for outdoor activities.
Very cosy comfortable top.
Perfect for everyday use as underwear, not just for sports when it's cold in winter.
Great wool tee! Feels great on the body, is heavy and does the job. Seems durable so far. Good value for money, would recommend over similar options from Decathlon
Deforms after the 2nd wash (30°C though)
Fits well, comfortable, perfect for winter and summer

Great under a t-shirt for climbing when it's not too hot, because the sleeves are tight and therefore don't bother you. In terms of smell, it's not incredible, but I imagine that's because it's not 100% merino.
I have known about wool products for a long time. I tried it out and found that the color is beautiful and the effect is good when worn.
Comfortable... I'll definitely buy it again if there's another color.
Size Guide

Additional Product Information
Composition
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: https://support.decathlon.co.uk/how-to-maintain-a-merino-wool-garment
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.
