Can't say enough good things about the fit on this underwear. -Andrew M, San Antonio TX

Fabric: Cool Cotton

  • Softest cotton fabric you will ever wear
  • Dries 4-5x faster than other brands
  • 86% Pima Cotton, 14% Spandex

History: Cotton is the most prevalent fiber in the world and is renowned for its breathability, strength and versatility.

Most of the men’s undergarment market uses only 100% cotton material. This is a strategy we believe to be deeply flawed. We begin with cotton, but also add stretch to the fabric for shape retention.

Problem: Traditional cotton undergarments tend to shrink up to a size smaller than you are, stick to the skin, cause you to overheat and sag when wet due to the weight of the fabric. They also stretch out over time, which cause an "A-frame" or "tented" appearance. It’s just a matter of time before these type of undergarments become rags for washing your car.

What we did: We found a super lightweight and smart fabric technology that uses a special cooling process to increase the absorption capacity of the fabric. Moisture is then transferred to the surface of the fabric where it easily and rapidly evaporates.

The non-pilling feature ensures garments retain softness and smoothness with NO PILLING; wash after wash.

What this means to you: Our Cool Cotton underwear remains as silky smooth as the day you bought them and keeps you cooler and drier than your traditional undergarments.

Wash after wash, your garment stays looking good as new, allowing you to continue wearing it for a very long time. Yes, this cooling technology is pretty awesome stuff!

Just like "Stern" says, these are life changing!

I never thought twice about underwear. I could've cared less. Then I heard Howard Stern talk about them. I'm so happy I got myself a couple pairs. I will be a life long customer! Do yourself a favor and get a pair, you will be amazed.

I am always trying different types of underwear and now I can stop searching. Tommy Johns are the best.

They are right

This is the most comfortable underwear I've ever owned. I don't have anything bad to say about it at all. The horizontal fly is a revelation. Thanks, folks!
