Product Insights
Under Armour's 6" Black Jersey Performance Boxerjock® 3-Pack delivers intense workout security with a seamless, pouchless fit that eliminates chafing, outperforming Saxx and David Archy for high-intensity movements like burpees and squats, while wicking sweat and offering an athletic, non-full-compression feel that some find smothering. Its cotton-rich blend (57% cotton) prioritizes softness over maximum moisture wicking, and at a sale per-pair cost of ~$13.30 (far less than competitors), value is strong, but premature wear—including holes, thinning, and seam fraying—is a durability tradeoff.
- Durability
Buyers report premature wear: holes, thinning, and seam fraying within months.

Multiple Reddit users report premature wear: one buyer observes that
all developed holes and fabric became see-through thin after less than a year

Why this is supported
Multiple reviewers in CrossFit and HIIT contexts confirm the Boxerjock's athletic cut keeps everything in place during dynamic leg movements.
A CrossFit user adds
while noting that pouch-less designs avoid the discomfort of internal seams. The snug fit can feel constricting for some, as one reviewer summarizes:

- Performance
Outperforms Saxx and David Archy for high-intensity workouts.
Why this is supported
The Boxerjock's tight, seamless front eliminates the pouch and chafing seams that some users find uncomfortable on competitors. One Reddit user directly stated:
I don’t think either Saxx or David Archy provide enough support for a workout. I started using Under Armour compression shorts last year and won’t workout without them anymore!
u/BasicTelevision5 in r/orangetheoryAnother reviewer confirmed the design holds everything in place without a pouch:
The Boxerjock has a tight, athletic fit but doesn’t feel like a compression short. It did a fine job of keeping everything in place, even without a pouch like the one on the Saxx.
outsideonline.comThe seamless construction also prevents moisture-trapping threads that cause chafing. The product is designed for both sports and everyday wear. Some users note a trade-off: while the compressive feel is ideal for workouts, it may be less comfortable for all-day wear compared to looser pouch designs. As one user put it:
the UAs did a good job minimizing that discomfort, but it’s still there.

Why this is supported

Compared To

UA compression shorts provide better support for workouts than Saxx, which some find inadequate for high-movement exercise.
vs David Archy
David Archy boxer briefs are comfortable but lack the support needed for workouts compared to UA.

UA compression shorts outperform Saxx and David Archy for workouts
Saxx are pretty nice, but I’ll say they are very expensive and don’t offer much advantage over other brands I have. The ballpark pouch is kind of a gimmick in my personal opinion. I really like the David Archy boxer briefs from Amazon. Adding on, I don’t think either Saxx or David Archy provide enough support for a workout. I started using Under Armour compression shorts last year and won’t workout without them anymore!

Fraying and holes in recent 3-pack Boxerjocks

UA Boxerjock minimizes discomfort but still compresses
Yeah, it's a give and a take. Thing about BBs is they always compress your junk, and I hate being smothered like that. Boxer shorts don't do that so badly. As I mentioned above, the UAs did a good job minimizing that discomfort, but it's still there.
