Well, the underwear is all cotton with very good quality but due to cost, the seams are average. The elastic can be seen in some areas from the inside. As for the fit, the medium size was perfect for me and it hasn't caused me any issues with tightness or allergies. I have bought many pieces mainly for work and they have made me look good. The label in the front only says <jokers> and the size. For the price of 1.5 euros, it's a steal, I highly recommend it.

Attention to the size selection. It has a tight fit, I normally wear large and I got XL for it to fit properly.

The size written is perhaps one or two sizes smaller, the quality is good in relation to the cost.

The cheapest thing you will find but its quality is fine, time will tell if it is durable.
The only complaint is the size, I ordered XL but it is something between Large and XL. However, it is comfortable and did not bother me.

If this is 3XXL, then I am Spider-Man!!!!!! The size is very small! It's like an L! Not even close to 3XXL by any means!!!!
