I actually bought a second package before trying the first and do not regret it! These are the most comfortable underwear I've ever owned. The waist fits right and hasn't rolled once!! They're soft, stretchy, not tight and pretty lightweight. My only gripe is they're supposed to be hand washed and dried, which is on me for looking at the price and not the fine print. Won't stop me from buying more, they're that comfy and I recommend highly.

All cotton. No swamp butt in this heat

Color: Black&grape Purple&ash Gray&white&pink&beige, Size: Medium

Absolutely love these!! All cotton, breathable and comfortable. A little too high waisted but I was expecting boy shorts not briefs. The front crotch seam is weird but doesn't show. Neither does anything else 😀

I loved them, they are very comfortable! I got them medium and they fit perfect! They do come a little small though.

Most comfortable underwear EVER!

Color: Black&grape Purple&ash Gray&white&pink&beige, Size: X-Large

As close to an actual men’s boxer brief you can get. Soft and stretchy but maintains their shape. The legs aren’t too tight and they don’t roll up and the waist doesn’t roll down. The box says to hand wash but who has time for that? They washed and dried just fine.
