These long johns surprised us.

We prototype lots of different pieces at Mr. Davis, but most of it never makes the cut. On a whim, we tried making a longer – to the ankles really – version of our classic bamboo underwear, and we knew the first time we tried it that we had a winner.

These long johns are just unbelievably comfortable. The key is that you wear them instead of your normal underwear whenever it’s going to be cold. Growing up, we only wore long johns when we were playing in the snow, skiing, hunting, or some other outdoor pursuit. The beauty of these is that they can be effectively worn as winter underwear. If the temp is less than 40 F, you’ll be more comfortable.

  • Buttery soft 96% Bamboo viscose / 4% Spandex.
  • Supple and stretchy to move with you.
  • Helps regulate body temperature via built in mesh.
  • Thin enough to wear anything from jeans to dress pants.

Anatomical Pouch

They fit just like our Standard Cut boxer briefs, so you get no-compromise support and fit with a (much) longer cut. 

Temperature Regulation

Inner-leg vents provide cool air flow where you need it most even as the bamboo fabric helps to keep you comfortable.

Premium Materials

Made from ultra premium materials throughout, we still charge far less than our competitors because our business model is designed around lower prices. 

The Secret to Cool Weather Comfort:

Wear Long Johns Every Day

Our premium fabric combination keeps you warm and comfortable when the temperature drops. When you wear our long johns, you'll work out more. You'll walk to lunch more. You'll be more comfortable lounging around the house. It's a better way to enjoy the winter.

Instructions for Use

You probably don't realize how cold legs make colder weather uncomfortable.

Follow these simple steps and you'll actually look forward to Winter weather.


Check the Weather.

If it's lower than 40 degrees Fahrenheit...

Wear these instead of normal underwear.

You can put on your jeans or trousers as usual.

Experience Thermal Bliss.

You'll be so much more comfortable. You can walk outside. You can wear them to the gym. You'll just wonder how you got through the winter before.

Better pricing is part of our philosophy.

If you're going to wear long johns frequently like we suggest, they can't be prohibitively expensive. We've built our business around lower prices than our competitors so that customers can come back when they need more. Other retailers have to charge more when they spend a fortune on branding, have sexy offices in big cities, and have investors who need to get paid back. We would rather not have outside investment, be in a boring Midwest office park, and rely on the word of mouth of our customers so that we can save you 50% and still make the most comfortable long johns you've ever worn.

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.
