The first time I ordered trunks from this company, I ordered my usual size LARGE. Compared to other brands, the waist seemed a little too snug for what I'm used to. This time around I ordered the next size up (X-LARGE 40-42), and the result is a little better fit. Even with the next size up, they still have a close contoured fit like the description says. In my opinion these trunks would be great for slender guys or young skinny guys. If you want some good looking underwear, but don't want to spend a fortune; these are perfect. Just be careful with your size and be prepared to order a size up.
