Very thin. You can see through it. It's not suitable for very cold weather. Especially with the machine in winter, you need very good clothing to say that you won't freeze... Very expensive for what it is... I saw MINERVA and got caught...

For 10€, it might be worth it. You get thermal for obvious reasons. How is it possible to have such a wide neck opening and have your chest sticking out? The XL might fit well for some short person. At 192 height and normal weight, the sleeves are short and generally the tank top is short. They either economized on the fabric or imported it directly from China.

It is an excellent thermal shirt for everyday use, as it does not have the feel of technical synthetic fabrics, but it is more skin-friendly. It is warm and at the same time comfortable like cotton. The skin does not sweat.

It is not something that generates heat, it maintains body temperature, you don't sweat, it isolates the ambient temperature at reasonable levels, not to wear it alone and go out in the snow. This undershirt, shirt+sweater, at 13°-16°C you're okay, if you want something better, go for a 70-dollar one if available and you're good, for its price, it's fine.

Good but it doesn't really catch my eye, it seems thin. Also, take a smaller size because in the size I got based on chest measurement, it is wide!

Comfortable and high-quality, it keeps me warm just like the more expensive thermal wear that I have from a mountaineering gear store

It is very good for thermal insulation and for polyester it allows the body to breathe well, while keeping you warm enough without sweating. I deduct one star because the fluffy feeling of the interior, although very nice in texture, fades and disappears after some washes
