Fantastic!
"Kumori underwear is always amazing. Second time ordering and always happy with it!"
-Andrew H
I have to say I really enjoy my new Bamboo briefs. It's so hard to find the right pair of underwear and these have been great to try out. For the boys that need a little room in the front and in the back without it looking saggy -> try these! Also the colors are great too!
I got a few pairs and one for my grandfather, and we loved them. I like a looser fit, so I sized up, and these were not only comfortable, but provided great support that you barely feel that you're wearing them.
Super high quality and I know where to go next time I need briefs!
WOW!!! These are the best brief I have ever worn. Fantastic fit Easy to wash and color fading not an issue.
The fabric is amazing nice and soft the cut is great just wish for a little more pouch space trying trunk next.
Great briefs. Feels like wearing nothing, but still well supported
