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

Finally boy shorts done right
Color: (6 Pack) Brown and Pink, Size: 5X-Large
So am going to be one of those, cause I do wished I had one of these reviews to fall on. First off, I am extremely picky about my panties. I am a large person. So comfort is a necessity. I have to have stretch, but also they have to be tight enough to not move or show things. I like longer legs, stretch, and seamless silky soft material. After YEARS of hunting, I did find some perfect ones from a big brand (Aerie) which are wildly overpriced at $23 per PAIR! Found these and they are perfect. Only difference is these have the thin waistband and the Aerie has the wide yoga waistband. I love these so much I bought 6 packs because I know how hard it’s to find the perfect boy shorts for larger women. Smooth, comfortable, seamless, long, and affordable! I did have to size up 2 sizes. In the other brand a xxxl is perfect.. I got a 5x in these. Probably could have went with the 4x but the 5x gives comfort. Im so glad I did find these.
