Quality control
Size: Large, Color: Black-4 Pack, Size: Large, Color: Black-4 Pack
They did fit well but now the waist band is coming off on all of them. Quality control needs to look into this problem. I would have bought them again if they solve this problem.

Great!
Size: Medium, Color: Multicolored19-4 Pack
I have ordered three packages of these over the years. They are solidly made and withstand washing and drying without the color fading and elastic band stretching. They are sized correctly and are super comfortable.

Cute, colorful underpants
Size: Medium, Color: A-multicolored-4 Pack
Bought these for my fiance because his old (other brand) ones were getting very tired. The price was great and they are brightly colored, which I get a kick out of. These do not bunch up while he's sitting, moving around, or pulling up his pants, and are comfortable with pants with a snugger fit around the legs and pelvis. They are soft, breathable, and durable, and have withstood numerous washes without an inkling of fading, tearing, and wear. I had some difficulties with the shipping and the original order never arrived, but this was immediately resolved after one contact with customer service. They were very responsive and sent out a fresh batch minutes later, which arrived very quickly and without any issue. Overall, impressed with the quality of both the underpants and the customer service.

KIND OF BAGGY
Size: Large, Color: A-multicolored-4 Pack
I guess I'm not built quite like the guy in the photo. I found these to be a little baggy. I buy briefs because I don't want baggy. They were, however, comfortable enough. I liked the wider waist band and the elastic was fine. I wouldn't buy them again though.
