As for quality, it gets 5/5.
However, the price would be more reasonable at €25 and not €30.
The fit is very good (I have the same one in short sleeves) and can be used in almost all sports, even on the bike or in the mountains as a first layer.

The shirt is good, the issue is that it is so thin that the body is visible from the inside and it is very unattractive. This is not apparent in the picture, so do not get the white one unless you wear it underneath another garment.

1. Tight fit as it should be! Some of you complain that it's too tight... that's how these things work...
2. Easy to wash. (by hand, of course) because some people put it in the washing machine and then complain...
3. It doesn't breathe 100% and that's good, otherwise it wouldn't work. If you want your body to breathe, wear blankets and do cardio.
4. Put it on and take it off after a workout, it has its own way, it's easy...
5. Give it time, eventually you will see that it works... I have been satisfied with this company.

Very tight fit and short in size. Take one size up. For winter there are better options, it doesn't work.

It is full of seams on the sides and low on the back, and when you sweat it becomes very uncomfortable. Additionally, the texture of the fabric is not bad, but it does not remind me of the characteristic UA texture, but rather a classic no brand thermal for 15 euros. If I hadn't bought it from an official representative, I would consider it an imitation and wouldn't even review it. For comparison, I got a size M and I am 175cm and 70 kg.
