Our Mission: Make the Best Sport Underwear Ever.

We discontinued our sport underwear last year not because it wasn’t good – customers really liked it – but because it could have been better. And it wasn’t different enough from our classic bamboo in terms of design to stand on its own. So we went back to the drawing board.

We’ve been testing dozens of fabrics for the last few years to find what functioned best. We’ve pared all those prototypes down to two very similar designs and now we’re looking for your fit and finish feedback. As a beta participant, you’ll get a great deal on amazing product, plus a survey after you’ve had them for a few weeks so you can tell us what you like and dislike.

Our goal is to end up with one final design the we can scale to the rest of our customers. We may end up using one fabric with elements of the other cut, or vice versa, so your feedback will really matter.

Beta 1: Black Polyamide Mesh
  • 72% Polyamide Mesh | 28% Spandex
  • Liner: Anti-odor | 59.9% regenerated cellulose fiber | 36.2%polyester | 3.9%polyamide
  • No-fly ovulated pouch with support and and lift with good air flow.
  • Traditional leg seam.
  • Unique, ultra-thin band.
  • Cut is between our Trunk and our Standard.
  • Sizes M-XL only for Beta.
Beta 2: Grey Poly Textured
  • 90% polyester | 10%spandex | Subtle Ridge Texture
  • Liner: Anti-odor | 59.9% regenerated cellulose fiber | 36.2%polyester | 3.9%polyamide
  • No-fly pouch with flat seams is more traditional in design.
  • Seamless leg cut is thinner.
  • Unique, ultra-thin band.
  • Cut is between our Trunk and our Standard.
  • Sizes M-XL only for Beta.
What we are looking for:
  • Honest feedback: We don’t want to make something that doesn’t stand out. The underwear market is crowded and we don’t need to make something just to do it. If you don’t like them for some reason tell us. It won’t hurt our feelings.
  • Specific feedback: If there is something you don’t like, the more specific you can be about it, the more it helps us. Do you like them for one activity but not another? Do you like one pouch style but the other leg style? Bury us in detail if you feel like it.
  • Endurance feedback: Don’t baby them. We washed and wore our classic bamboo underwear for a year to make sure they held up before we sold them. If these are going to fail, we want you to find out how.

Beta Style Details

Both beta options are about the same cut – something in between our standard and our trunk – offering good support, out-of-this-world moisture management, and dramatic weight savings. When you pack multiple pairs of underwear the weight really adds (or doesn’t add) up – a full week’s worth of our these weighs about 8 ounces total. The key differences are in the fabric, the pouch, and the leg. They fit very similarly but we are interested to see if customers have any preferences in aggregate.

Black Polyamide Mesh

  • 72% Polyamide Mesh | 28% Spandex
  • Liner: Anti-odor | 59.9% regenerated cellulose fiber | 36.2%polyester | 3.9%polyamide
  • No-fly ovulated pouch with support and and lift with good air flow.
  • Traditional leg seam.
  • Unique, ultra-thin band.
  • Cut is between our Trunk and our Standard.
  • Sizes M-XL only for Beta.

Grey Poly Textured

  • 90% polyester | 10%spandex | Subtle Ridge Texture
  • Liner: Anti-odor | 59.9% regenerated cellulose fiber | 36.2%polyester | 3.9%polyamide
  • No-fly pouch with flat seams is more traditional in design.

Ultra-Ultralight

At just 1.2 oz (34 grams) in a medium, these weigh 50-70% less than leading lightweight underwear from Ex Officio and Patagonia.

Incredible Moisture Management

Both beta fabrics wick moisture away and dry incredibly quickly. Perfect for athletic pursuits or travel.

Premium Materials

To make great, incredibly comfortable underwear, you have to use premium fabrics and methods. We do, so your Mr. Davis will last for years.

We've got two new designs, but need your feedback.

Join the beta and help us refine our design.

We've been working on a new sport underwear design for the last 18 months. We're down to two final cut and fabric options, but we need to get feedback from real customers on what they like and dislike, and we want to see how they fit more body types. Purchase a beta pack today and you get an incredible price and the opportunity to influence the final design.

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.

Gary M.Grey Bamboo Trunks Cut, Mid Cut

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!

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

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

Reed C.Grey Bamboo Trunks, Mid and Standard 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.

Robert B.Grey Bamboo Mid 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.

NadiyahGrey Bamboo 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.

Macsen V.Grey, Navy Sport Standard 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!!

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

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

Zachary J.Navy Sport, Bamboo Trunks 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!!!

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

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

Aaron B.Navy Bamboo Trunks 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.

Macsen V.Grey, Navy Sport Standard Cut

Feels Lighter than Air

  • Both our designs are incredibly, almost unnervingly light and thin.
  • Our fabrics allow air and moisture to move freely, so you stay dry.
  • Because they are so thin, they can be worn under tights or athletic shorts to provide more support.
  • The band too, is made of technical materials that shed moisture and don’t bind.

Limited Beta: Don't Miss Out

Our last beta program sold out all pairs within hours. Don’t hesitate or you may miss out on the opportunity as quantities are very limited.

Frequently Asked Questions

If we haven’t answered your questions here, hit our chat icon or email us at support@mrdavis.com

What's your return policy?

On the beta program, we’ll work with you if you end up with the wrong sized product, but if something is wrong, we’ll either refund or replace your underwear.  No return required. 

Otherwise our standard return policy does not apply, as these are a one-time purchase with no returns.

Does Mr. Davis offer free exchanges?

On non beta product we do: If you have issues with sizing or selection we provide FREE shipping both ways on exchanges (US only) 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.

On Beta pairs, we don’t have enough quantity to guarantee exchanges, so our traditional return and exchange policy does not apply. If you have an issue, email us and we’ll try to work something out.

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. One of the big reasons we’re doing this beta program is that it’s way easier to find weakness when lots of people use something instead of just with our own testing. So let us know if our beta styles and fabrics don’t meet our quality expectations.

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!

What payment methods do you accept?

We accept Visa, MasterCard, Discover and American Express. Email us at support@mrdavis.com if you need to make special payment arrangements.
