For a man 1.82 m tall and 85 kg, the 3XL fits well. For the price, I consider them worth the money, especially if someone wants an economical package for everyday use. The quality of the fabric, of course, is not at the level of more expensive branded options and they feel somewhat stiffer. Nevertheless, they are durable and hold up well in use and washing. Overall, good value for money.

Good quality but definitely 2 sizes larger than what you usually wear.
The LARGE was worn by a slim 15-year-old teenager.

For Chinese underwear... they're okay!!!!! However, from the size you usually wear, calculate 2-3 sizes up, if not more. For example, I wear 2XL because I want comfort and I got these in my second order in 6XL to feel comfortable.

The quality is Chinese. You get what you pay for. As for the sizes... Definitely 2 sizes smaller than normal and almost 3. So get a bigger one. Each color trio also has 3 different sizes. I got the 6XL and each trio had 4XL, 5XL, 6XL. The 5XL is for someone who wears W44 pants in American sizing.

While I usually wear medium/large, I bought the large size to make sure it would fit me, and it turned out to be very small. I would describe it as small. Unfortunately, they are not returnable, so they are useless to me.
