About Saxx Underwear

Saxx was created out of a need for comfort and a disdain for discomfort. If you’d like to read a little more about their story, click here. Their tagline is “Life Changing Underwear” which is a bold, albeit strange statement about underwear. I’ll see if there is any life change as I test these out over the next three months.

Price: None of their products are cheap (their lowest MSRP is $26.95), but they are comparable to the prices of other performance underwear in the same segment.

About ME

I have big legs. So for the most part, all boxer-brief style underwear will ride up my legs and bunch uncomfortably. I’ve just recently purchased and returned two major brands for this very reason.

Many of you have heard of being “hangry” which is the combination of hungry and angry. Well, I get hangry, but it’s because I am hot and angry. Because of this, breathability is also very important when I am looking for a pair of underwear.

Lastly, my wife accuses me of keeping my “drawers” (as we say in the south) a little bit past their expiration date.  I argue that the ones I keep are both comfortable and durable. So durability is also important when choosing underwear.

To recap, I look for three main things when it comes to underwear:

  • Comfort
  • Breathability
  • Durability

The Product

Saxx Kinetic Boxer Briefs


This is how Saxx describes the Kinetic Boxer Brief: “built for high-output activities like marathon training sessions or blistering hot backcountry runs.” So these aren’t your everyday underwear, but rather more for activities where you’ll be moving a round a lot.



  • Moisture-wicking 90% nylon / 10% spandex fabric
  • Patented BallPark Pouch™ for friction-free support
  • Three-D Fit™ with 9-panel construction
  • Non-chafing Flat Out Seams
  • Anti-microbial technology keeps odors at bay
  • Raised silicone SAXX logo at front waistband
  • 1¾” anti-roll moisture-wicking jacquard waistband
  • Semi-Compression Fit
  • 5″ inseam
  • No fly
  • Imported

BallPark Pouch: Described as a “hammock shaped pouch”, these underwear have a specifically designed compartment that prevents any skin-to-skin contact and keeps everything in place. I’ll let you read between the lines on this one, but let’s just say this pouch seeks to solve a big complaint by many with traditional underwear design.

Three-D Fit: 9 Panels of fabric are used in order to account for the differences in shape of glutes, thighs, hamstrings, and quads to ensure the best possible and most comfortable fit.

Flat Out Seams: Saxx places the raised edge of the seams on the outside of the underwear, rather than on the outside. This should reduce any kind of friction from the seams and make them more comfortable.

Planned Field Testing:

I plan on wearing the Kinetic Underwear for a variety of activities in the next month before my next review:

  • Workouts at the Gym
  • Running
  • Hiking
  • Backpacking

Thanks to Saxx and 4All Outdoors for the chance to try the Kinetic Underwear. Check back in about a month for my update and thoughts on how they have performed so far.
