husband loves!!

"bought these for my husband and he always reaches for them! they're shorter than normal briefs but they stay in place well and he says they're really breathable. would repurchase for sure!!"

— Summer L. (5/5)

Not durable

"I’m disappointed in the durability of this underwear. After a bit over a year of using this underwear, I am sorry to say that there are holes in the crotch. I wear each pair about once every 3 weeks on average so it’s not like I’m wearing them very often. They look and feel nice but they do not last as long as underwear this expensive should."

— Kel B. (5/5)

Soft fabric and very comfortable

Run Small

"The fabric is great but they run a bit small and the cotton shrinks over time. I would recommend to size up. Otherwise great product!"
