Pros: Great pouch, amazing fabric, great design 

Cons: May not be the best for sports, some may not like the leg straps

UNB Tim recommendation: A good jock for everyday wear. You could wear for sports but it’s more of a fashion jock. The pouch is amazing great for guys who need the extra room in the front. I liked the leg straps, they are smaller than traditional jocks. 


I have said it before but I love Cocksox. Their underwear just fits me like a glove and feels amazing. The pouch is very high on my favorites list. So, when I get a chance to review new Cocksox, I am so excited to do so. I have a Cocksox Jock in my collection. It has bee one of my favorite jocks to wear. When I got this new one I was excited.

I knew I needed to put this through a test. The other jock I have fits great and I know what it can handle. This one I wore to work and a day I had to move some stuff. While I was doing my work and errands, the pair really felt amazing. The pouch doesn’t fit as great as the CXO1. This is due to the design, the leg straps don’t provide the same stability as the brief. However, it still has a great pouch, you can’t go wrong with a Cocksox pouch.

Two things that they do well with are construction and fabric. Over the last 10 year’s they have perfected the formula for amazing fitting underwear in the most awesome fabric. They get two thumbs way up! As for sizing, as long as you follow the sizing guide there should be no issues. Their sizing has been pretty standard over the last several years.

All in all, this is a great jock. It’s a great design with smaller leg straps than other jocks. This is a bonus for me but many may not like them. I would suggest for every day wear over sports. However, you could easily wear it to the gym.

  1. I have been reading all of the UNB reviews of Cocksox and finally ordered a couple of pairs to give them a try. I ordered the CX21N Jock & Brief. I have to agree with everything written with the exception of the pouch. I found the pouch to be big and sloppy. You literally are just hanging, with zero support of any king, the pouch felt like a boxer. Sorry, but for me a jock and brief should provide some kind of support. So I would agree with all 9’s across the board and a 1 for the pouch.

    • Sorry you had an issue with the pouch. I haven’t had that issue the support has been awesome for me in Cocksox. It’s one of my favorite pouches. Keep reading and I”m sure we’ll share something that fits better
