It is slim fit, generally it is somewhat tight and the fabric is very thin. Do not expect thick fabric. That's why the price is low, I believe.

I ordered the medium size, just like in other Adidas forms that fit me, but when I wore it, it felt like I ordered an XL. Obviously, it's only suitable for pajamas

Unfortunately, the pants I bought were made in Pakistan and were not as good as the ones from a well-known chain that were made in Indonesia, but much better.
