Nice fit and feel

I ordered the red trunks, size XL by mistake (and they were out of large). The XL’s still fit fine and the material and fit feel great.
I sure wish TBO would keep size large of the red trunks but they’ve been out of stock EVERY time I’ve chkd.

These are a really good fit

These are a really good fit. They stay in place and work well with gym shorts that can have a slippery waist band, a problem when shorts under have the same type of waist band. Reasonable price, size is correct, shipping...well to out of three not bad. A grade material, design, fit. C grade for shipping.

Buyer beware!

This company is trash. I gave them my info for a discount code and the code didn’t work. I reached out to them and they were of no help. For the record, the underwear is amazing but it’s run by bait and switch con artist

Mostly excellent a little bit of complaining

OK, let me be fair and whatever I say that seems negative is just honest. I love them overall. I love the underwear. They feel like air like nothing is on and they’re very sexy. I’m not supposed to say that, though the only problems I had was at the bottom of each leg they’ve gotten sort of stretched out already. They’re not firm and like for example the blue looks unbelievable, shiny and bright on my cell phone when I got it. It looks great, but it doesn’t look as shiny and bright as what you’re presenting, but overall, I’d give you a great remarks great reviews..

The product was great but it took twice as long to be delivered as told and the customs significantly added to the price.
