All our cuts feature size-matched inseams. With an inseam of 2-3.5″ depending on the size, and a short rise, the trunk cut hides under almost anything and provides a snug and supportive pouch fit without feeling constrictive.
Designed to match the length of a “standard” boxer briefs you might experienced in the past. They feature a traditional rise with a size-matched inseam ranging from 4.5″ to 6.5″, depending on your size. The pouch provides some lift and skin separation but not as much as the Trunk cut.

Anatomical Pouch

Roomy pouch shape gently lifts your package to reduce skin on skin contact. Life changing, adjustment free comfort.

Cooling Airflow

Hidden vents provide cool air flow where you need it most. As you move, air flows in and out keep you dry.

Premium Materials

To make great, incredibly comfortable underwear, you have to use premium fabrics, so we do.

The Best Fabric You've Never Felt

  • Stretch Bamboo Viscose is 3-4x softer than cotton and much nicer than Modal, which some of our competitors offer (at higher prices we might add). We think it’s the perfect every-day fabric for underwear and our customers agree.
  • Our 110 gsm Polyamide Venting fabric is so air permeable you can actually feel little puffs of air on your nether regions. The air flow helps minimize moisture accumulation.
  • Premium band elastics won’t bind or fold and last for years of heavy washing.
  • All in all, you’ll forget you’re wearing our drawers. You’ll just be more comfortable.

The Trunk Cut

All our cuts feature size-matched inseams. With an inseam of 2-3.5" depending on the size, and a short rise, the trunk cut hides under almost anything and provides a snug and supportive pouch fit. If you like a pouch with some lift, go with the Trunk.

The Standard Cut

Designed to match the length of a "standard" boxer briefs you might experienced in the past. They feature the same rise as our mid-cut and a size-matched inseam ranging from 4.5" to 6.5", depending on your size. Pouch provides light lift, but is not as snug as the Trunk.

Gary M.Grey Bamboo Trunks Cut, Mid Cut

Received mine a week ago, I absolutely LOVE them, they are incredible. By far the best underwear I've ever owned.

Gary M.Grey Bamboo Trunks Cut, Mid Cut

They look sexy and feel amazing. Hopefully they hold up well. I just opted for the 3 pack but I want more, I never want to wear another brand again.

To anyone hesitating on getting either the undershirts or the new underwear... STOP RIGHT NOW!! This is the best product you can find, plus the price is more than reasonable!

Reed C.Grey Bamboo Trunks, Mid and Standard Cut

All fits are amazing. Now I know where to get underwear for the rest of my life.

Robert B.Grey Bamboo Mid Cut

MUCH more comfortable than my 2xist. I need extra support in the form of anatomical pouch...this pouch provides great support without pinching. I'm very excited with this pair and plan on replacing all of my 2xist with Mr. Davis.

Got these for my boyfriend. Says they're the best underwear he's ever worn/owned. Thanks again! He's never been a happy customer in the underwear department.

These underwear are absolutely great. I have several other pairs of premium underwear from other manufacturers and these are either on par or surpass at a great price point. Can't wait to purchase more from Mr Davis. Great work guys!!!

Aaron B.Navy Bamboo Trunks Cut

Thanks for the great customer service. Your products are much better than Mack Weldon.

Macsen V.Grey, Navy Sport Standard Cut

Most undies get uncomfortable as the day goes on. I never even thought about these until I got home and took em off to shower.

What is the fabric composition of the underwear?

Our underwear body is composed of 96% bamboo viscose and 4% spandex, while the venting between legs is 110gsm Polyamide.

Are Mr. Davis Underwear Built to Last?

Absolutely. We have a motto around here: Buy it for Life. We’re tired of companies making stuff that you have to throw away after a season or two. Our underwear is made from great materials and will hold up very well to every day use. If you follow our care instructions our underwear can last for years. If you ever experience any defect in workmanship outside of normal wear and tear, email us a picture and we’ll replace them.

How do Mr. Davis Underwear fit so well?

Because we obsessed over the details to get the fit just right. Our underwear are designed to be a little snug but delightfully comfortable, so you get the support you need without pinching or riding up.

Our Magical Pouch design gently lifts your package to prevent skin on skin contact, chafing and the need to constantly adjust. Once you try our underwear you’ll never want to go back to normal underwear.

How should I wash my Mr. Davis Underwear?

Heat is generally the enemy of fabrics and Mr. Davis is no different. We advise you wash and dry on cool if possible. If you don’t, your products will still last, but may fade or shrink a bit.

Do you ship worldwide?

We ship to more or less the whole world. Our full country list is on our cart page. Just select the drop down and hopefully we’ll be shipping you something soon!
