Review Summary

10 Reviews

First try at the 9"

I've had numerous versions on the 6" Performance boxer briefs, with the originals, years ago, being my favorite. Due to a house fire I had to replace all of them and decided to give these a try. Some comments mentioned them falling down. I have not had this issue. These live up to the Microthread feel of being softer than most other materials, breathable and super comfortable. I up size the boxer briefs for a more relaxed feel. I normally wear a 36x30 pant and Large shirts. I ordered these in XL and are the perfect fit and my go to briefs now. I started with 3 pairs and have 5 now.

Fit comfortable

Great fit and very comfortable not too tight or too loose, 9” is perfect.

Good fit

I use these for work, 12 hour shifts going up and down stairs/ladders in a factory that's always hot. They breath well and haven't had any issues with the leg riding up or the waist band down, being a bigger guy those were two of my main concerns and these answered the call like a champ

Good Fit

I bought these mainly because I do a lot of walking at work. 3 miles or more and they are very comfortable. [This review was collected as part of a promotion.]

Great quality

This is a comfortable boxerjock. Wore it for a 10 hour working day with no issues. I prefer the mid length boxerjock but this one was just fine. [This review was collected as part of a promotion.]

Very comfortable!

The fit is just right and the pouch holds everything in place. They also don’t ride up !! [This review was collected as part of a promotion.]

Close to the old Charged Cotton

The microthread boxerjock is the closest to the original Charged Cotton boxerjock in comfort and performance. They fit slightly smaller than the original boxerjock, but the overall comfort is good. Would love to see a multipack in 9 inch for additional savings. [This review was collected as part of a promotion.]

Not That Bad

These underwear are very comfortable. I haven't had any issues with them riding up on the leg or falling down at the waist. So far so good but only been a month.

Wanted to like these, but can't

Tried these as a replacement to the "original" 9 in. boxerjocks (which were perfection before they changed). These follow the same Made in Bangladesh template--legs are tight, fall down way too easily, and are very very thin. I'm keeping one to try out longer term, but I don't see myself ordering any more of these.


Bought these since the UA Cupron seemed to be discontinued, which were my go to underwear ever since UA decided to jack-up the original boxer jock and make them low rise women’s underwear. I’m a larger guy, 6’1, 260, and like the 9in underwear they don’t ride up and fit on the waist. These are not what I was looking for. These ride low on the hips, pull up at the thighs, and are very thin. If you’re a fan of the “original” boxer jock and/or the Cupron boxerjocks that fit at the waist and the leg don’t rise up, then you will not like these.
