Great for the Price!
Color: Black, Size: Medium
These are great briefs for the price. They fit nicely, are comfortable and hold up wash after wash. I have ordered Wirarpa underwear for my husband and myself for several years.

I recommend them
Color: Black/Deep Blue/Red/Deep Grey, Size: Small
I bought it for my 11-year-old son who is 5'4" tall and weighs 124 pounds, and they fit him perfectly. It doesn't roll up and it has good elasticity
