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.

Comfortable and secure
Size: Small, Color: Black Grey
Nice quality non fly men’s underwear. Pouch holds your gear firmly. Ordered small (30” waist) but ended up ordering same item in medium for more comfort. Also went with the cotton version.

Comfortable & well-fitting, but some differences in stiffness between batches
Size: Medium, Color: Black/Deep Blue/Deep Grey/Heather Grey
I've basically been exclusively buying these since I've discovered them. Super-comfortable and maintain their shape for a long time, but I've noticed from buying it multiple times that sometimes the pouch area has stiffer texture and more support than other times (when it's loose & stretchy like the rest of it). I wish I could specify receiving the more-supported ones because they tend to produce less....how to say, knocking the boys around.
