Saxx Kinetic Boxer Performance Underwear

Final Update: 10/26/17

I’ve had the the Kinetic Boxers for about three months now. I’ve used them:

  • Running
  • Working out
  • Backpacking
  • Everyday use

Since my last update I was able to use them during a backpacking trip. I made sure to wear them on the day where we logged the most mileage. That day, we hiked for about 8 or so hours and covered about 12 miles (slow, I know).  The temps were moderate, in the mid 70’s. The boxers were comfortable, didn’t ride up, and kept me from chafing the entire day.

In my initial post, I mentioned that I was going to be considering three things when testing out the Saxx Kinetic Boxers: comfort, breathability, and durability.

Comfort: A-*

The boxers were comfortable when I was active. They kept everything it’s it’s place (kudos to the BallPark Pouch), didn’t ride up my legs, and didn’t have me constantly adjusting and picking at the underwear.

*The boxers weren’t comfortable when not active. I know that this seems a little counterintuitive, but it was something that annoyed me about them. I tried to wear them a few times to the office, or just around town and found them to be a little too constrictive for casual wear. They weren’t made for everyday casual use, so I didn’t ding them for that, but still not a pair I would wear unless I was using them specifically for being active.

Breathability: A

No complaints here. The boxers breathed well and never seemed to be any hotter than they should have been.

Durability: A+

In my last update, I noted a couple of spots where the fabric had pulled. I haven’t noticed any more instances of this. The boxers have held up and haven’t shown any sign of wear or damage.


The Saxx Kinetic Boxer Briefs did what they were made to do: keep you comfortable during vigorous activity. The feature that I liked best with the underwear and what really sets them apart from other compression type underwear is the BallPark Pouch. It creates a separate compartment which keeps your legs away from your “business” – eliminating a few different kinds of discomfort that are so common when heat and physical exertion are combined.

Thanks again to Saxx and 4All Outdoors for the chance to review the Kinetic Boxers!

Update: 9/20/17

I’ve been able to wear the Kinetic Boxer on numerous occasions over the past month: running, working out, while doing yard work, and even as my underwear while working my office job.

A little nervous:

I wore the underwear a few times just as I would wear to work before I had a chance to really test them out for what they were made for. It made me a little nervous. I didn’t find them very comfortable, they rode up my legs a little bit, and I found myself having to “adjust” more than I would when I wear my “normal” cotton underwear. This made me a little nervous. My initial thought was that if they were uncomfortable when I wasn’t active, then they would be uncomfortable when I was active.


I first wore the Kinetic boxer briefs to work out in. Keep in mind that I live in the Upstate of South Carolina (Greenville), so temps have been in the mid 80s to low 90s still. I forgot that I even had them on. This is a big deal. They were comfortable, breathable, and kept everything in place while I did some Crossfit style workouts at my local Y.

I have also been on a number of runs with them so far. They have been low mileage (5 mi or less), but nevertheless, the underwear performed really well. As I mentioned above, they were comfortable (read: I didn’t have to constantly do any adjusting) and they kept me from any discomfort like chafing in the warmer weather.

Trying to find something wrong:

As I mentioned in my initial post, I am looking at comfort, breathability, and durability while testing the Kinetic Boxer Briefs out. I have highlighted the comfort and breathability in the above sections and wanted to give an update on the durability portion. I had to look very hard to find any issues with degradation or breakdown. Below are a couple of photos. One will show how the label on the inside of the band is starting to wear off (not a big deal) and the other shows a small pick in the fabric which I had to look very hard to find. So after a month, these underwear are holding up well!

Check back in a month or so for my final update on the Kinetic Boxer Briefs. I plan on taking them on at least a backpacking trip up into the Blue Ridge Mountains.

Initial Review: 7/18/17

Underwear Review Disclaimer: While reading this review, some topics will be discussed that I would leave out when considering conversation starters at dinner with your in-laws.

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.
