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. 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.

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

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

NadiyahGrey Bamboo Standard Cut

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.

Macsen V.Grey, Navy Sport Standard Cut

LOVE THEM! Got them in the mail on Monday and wore them at work all day yesterday. I do landscaping so I sweat all day long. 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.

Jean-Sebastien D.Grey Bamboo Mid Cut, Trunks Cut

Got mine on monday, and just like my Mr. Davis undershirts, they are the most comfortable piece of clothing I have ever worn !! Wow, I will be ordering more for sure!! 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!

Zachary J.Navy Sport, Bamboo Trunks Cut

wow. just like the shirts. Your undies are great.

Tyler Grey, Navy Bamboo Standard Cut

Fantastic product, just amazing! Extremely soft comfortable material, form fitting, not restrictive and very breathable. It's literally a climate controlled protective layer that completely tightens and smooths out your appearance. I consider myself a connoisseur of men's clothing and I have to admit the quality, style, fit and feel of these products surpassed my every expectation. Great Value for the price. I will forever be a lifetime buyer and supporter of your products.

Paul M.Navy Sport Trunks Cut, Navy Bamboo Mid Cut

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.

What Makes Mr. Davis the Best?

We spent two years refining dozens of underwear prototypes to bring you the best fitting, most comfortable underwear you've ever tried.

The Best Fabrics

You can't make good underwear from bad fabrics. Our poly sport fabric wicks moisture away like it was never there and never pills. High quality elastics take years of wear without flinching.

Maximum Airflow

To keep you cool and dry, our hidden venting allows for maximum air flow where you need it most. When you move, air flows in and out to drain the swamp.

Closeout Pricing

We're retiring this design of sport underwear, so this is your chance to grab them for nearly half off.

Built to Last

Good underwear should last for years, and our premium fabrics hold up to everyday wear. If you find any defect in our underwear, just email us and we'll replace it. For longest life and maximum comfort, wash and dry on cold.

Direct to You Value

Unlike most brands, who sell through retail chains, we sell direct to you to offer lower prices. Underwear with equivalent fabrics and finishes cost 50-100% more at retail stores.

100 Day Free Returns

Our priority is getting you into the right fit, even if that means an exchange. If the fit's just not right for you we offer free returns on any unworn merchandise for up to 100 days.

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 the most snug and supportive fit of all of our cuts.

The Mid-Cut

Our mid-cut features a size-matched 3-4.5" inseam and an additional inch of rise compared to our trunks. This means you still get support, but the fit is not quite as snug.

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 4.25" to 6.25", depending on your size.

About our Fabrics

Our Wicking Poly Sport fabric offers light compression, zero pilling and excellent moisture management. It’s a great option for travel or sport.

Our 10 gsm Polyamide Venting fabric, which is used on underside of all Mr. Davis underwear, is so air-permeable you can actually feel little puffs of air on your nether regions. The air flow helps minimize moisture accumulation.

Mr. Davis is made from great materials and will hold up to every day use. If you follow our care instructions our underwear can last for years. If experience any defect in workmanship within two years, we’ll replace the defective underwear.


Mr. Davis underwear are designed to be snug but comfortable, so you get the support you need without pinching or riding up.



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 just won’t last quite as long.



We’ve made the program really easy to tune to your personal needs.  A week or so before we ship any product to you, we’ll send you an email to let you know a shipment is coming soon.  If you’re not ready, just click the SNOOZE button in the email and we’ll delay your shipment by two months. You can snooze as often as you’d like.


You can pause your membership at any time with just a few clicks.

To pause, log in to your account at  From there click on the VIP Settings tab and you can snooze, pause or cancel any active memberships.

If you don’t want to do this yourself, you can send an email to and we’ll pause for you.


If you don’t love your first pair of underwear, Mr. Davis will ship you a new size/style or issue a refund. No return required. To initiate a return or exchange, visit our return policy page.

For remaining pairs, we offer free returns and exchanges for unused, unworn and unwashed merchandise within 100 days of your order (US customers only). Here’s the process:

  1. First, you must contact us at to obtain approval for the return. If you send us a return without an RA#, we will not be able to process it.
  2. Upon approving your return, we’ll send you a prepaid shipping label including the RA#.
  3. Once we receive your item, we’ll process your return and refund your card for your purchase price.


If you have issues with sizing or selection we provide FREE shipping both ways (US only) on exchanges of your Mr. Davis to get you in the right product. We use the same process we do for returns. We cannot exchange international orders at this time.


Mr. Davis is all about optimizing our cost structure to deliver value to you, and one of the best ways we can do that is by being able to predict future orders. When you become a Mr. Davis VIP Member, you’ll be set up to automatically receive your products on a fixed interval. This allows us to better estimate how much product we need to make ahead of time, which means we can save money. We pass that savings on to you in the form of a big discount.

As long as you maintain active VIP membership (and you can skip shipments as often as you’d like), you’ll be locked into your original pricing, even if prices go up in the future.


We accept Visa, MasterCard, American Express and Discover. If you need to arrange for other payment methods, we may be able to accommodate you if you contact us at
