We make sad men happy, and happy men happier!

Our original design in a knitted shark skin grey fabric. These are comfy and "loungey" (is that a word?) This is our original comfort sack with no-fly design. Great for all day wear and kicking back.

With our proprietary wrap-around comfort-sack design, we have created the ultimate ball-pouch boxer brief. Our briefs envelop your man-parts in a Lazy-boy lounger of masculine comfort, making these the most comfortable men's boxer briefs around.

We make our "comfort-sack" of breathable tech-mesh that not only creates the most breathable men's underwear, but is designed to allow your boys to hang naturally providing a truly "natural fit." This keeps your boys cool and dry—the way men's underwear was supposed to fit.

We make these bad-boys with superior quality durable tech-fabric which are made to last. An extra sturdy and plush jacquard waistband keeps your briefs and your boys in place. Get your hands on these and you will feel their unique quality.

The UNDERWARE design features include:

  • Proprietary natural hanging "comfort-sack" designed for a natural fit— men were meant to hang!
  • High quality soft but durable tech fabric to go the distance
  • Moisture wicking quick-dry tech fabric to keep you cool and dry
  • Breathable mesh in the wrap-around comfort sack and crotch panels
  • No more "fixing yourself" all-day
  • Never have your boys stuck to your leg ever again!

Our unique ball pouch is double the protection. We wrap both the inner thigh and your man-parts separately creating our exclusive cloth-on-cloth. double protection that puts an end to chafing. Compare our design to our competitors like Saxx, Tommy John, Under Armour, and Shinesty, and you will feel the immediate difference!



We use industry standard sizing, but differences in fabric make a difference in fit. Please measure your waist in inches, and they will be sure to fit! — Never rely on the titles "Small," "Large," etc.

    Available in S, M, L, XL, XXL, & XXXL Sizes (Waist sizes in inches)

    • SMALL — 28–30
    • MEDIUM — 31–33
    • LARGE — 34–36

      Perfect in all aspects...

      Very comfortable. Like the "breathing"... Like the colors offered. Like the fit - overall! Like the small footprint when packing for a trip.

      Best supportive Underwear

      Really love these underwear. Very Comfortable to wear and the pouch is very supportive keeping everything in place no matter what movement you are doing. New favorite underwear to wear.

      They are very comfortable, but I think the pouch should be slightly bigger. I ride a motorcycle and don't want to be sitting on my boys. Very good product.

      Happy boys

      I bought for me, my sons, and coworkers. From purchase to receipt, all went well. Everyone is happy. In fact, my coworker gave his (unopened) pair to his son (because the gift he ordered before he had heard of UnderwareUSA) hadn't arrived. Then after the "real" gift arrived, his son wouldn't trade the Underware for his "real" gift. His boy's boys had a newfound happiness they weren't giving up.
