Well designed sweater, the collar is high, the zip opens wide so good ventilation without having to remove it, the parts under the armpits are in a finer fabric so less perspiration, and the "mitten" sleeves are practical to avoid taking out the pair of gloves in case of a little cold
I checked the date and I've had this blouse for 4 years. I wear it regularly and often, not only for sports but also every day. I ride horses in it, camp in it, take it to the mountains, on long-distance trails, to bonfires, I've washed it many times and it's still holding up great. It's true that it's a bit faded and not very fluffy, but that doesn't bother me. The price is a bit high, but when I think about how many times I've worn it over the years, I think it's worth buying one rather than several that will quickly wear out.
This is my second color of this model, it works great for trekking and everyday thanks to the nice design it looks completely fine in everyday life, not only on the trail. It is warm, does not pill much, my previous one is already 2-3 years old and is worn, although a bit more compact and faded than the new one but it still holds up great, I will continue to use it and maybe buy another one.
This shirt is my absolute favorite for trekking! Merino wool is amazing - warm but not too hot, and you don't smell bad even after a few days of wearing it. It fits your body perfectly and is very comfortable. I recommend it to every mountain hiking enthusiast.
Good quality. Warm wool top, yet very soft (I wear it easily even though I generally can't stand wool clothes) Good cut. No information to share regarding washing resistance, as it has not been worn very much yet.
Lightweight merino wool sweater. Tested for hiking and skiing. Moisture wicking, no sweat odor. Soft and comfortable to wear.
Comfortable hiking shoes.
The size fits. It doesn't pill, a suitable warm layer. The color is so bland, but I don't mind that at all
This is a proper thick merino wool base layer, not a mid-layer. You could use it as a mid-layer, but you should go one size up. I used this for a 10km hike in +2°C, combined with other layers, and felt warm and comfortable-no sweat or odor
The fabric under the arms has stitches that run from the seam. The sweater was worn 4 times a week and maintained according to the instructions. I do not recommend this product.
Used for skiing, it keeps you warm while wicking away perspiration very well, very good product.
practical and elegant sweater for sportswear. very good odor control but the white color gets dirty quickly when bivouacking
Fits me very well, comfortable to wear
Great for skiing!
Versatile garment. I use it both indoors and outdoors. Very popular for winter sports such as cross-country skiing.

Additional Product Information
Composition
Main fabric: 48.0% Wool, 31.0% Polyester, 21.0% Acrylic ; Yoke: 86.0% Wool, 14.0% Polyamide
What are the additional features of this t-shirt?

What are the advantages of merino wool after exercise?
When you push yourself physically and sweat heavily, 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 important 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.
How do i wash my merino wool t-shirt?
We recommend you machine wash your Merino wool T-shirt at 30° on a normal cycle. Preferably use liquid detergent designed to clean wool clothing. Dry flat, never tumble dry.For more information: https://support.decathlon.co.uk/how-to-maintain-a-merino-wool-garment
