UNB Tim recommendation: LOVED this pair. I had a few slight issues but none that detracted from my experience. The waistband and fit were two things I loved the most. I wore this to a 5K Walk/Run and it was the perfect pair to wear! It proves that you can wear a Cocksox Jock for more than just fashion!

A few months ago I wrote the post that this jock by Cocksox was my favorite jock. Now with the update for the Lustrous Elements Collection, I was excited to try this again. The metallic waistband is something I LOVE! This time i was putting this to the test via a 5K walk/run! Would this still be my favorite jock? Time would tell.

As I mentioned above, this pair was worn for something active. I had a 5K walk/run to attend and figured why not wear the jock! Most of the day I wore them to work. At work, they really weren’t tested. After work, it was on. I’m getting back in shape and was talked into the walk. The support was perfect for the event. I barely noticed I was wearing underwear, which is a good thing. I did have some issues with the waistband rolling some. I don’t know if this was because of the metallic band. Because my other one doesn’t do this. Regardless I didn’t notice it through out the activity.

This pair is made with the amazing fabric that Cocksox is known for! 92% Supplex® 8% Lycra® blend always feels awesome. It’s super soft and fits like a glove. The pouch is in my top 5 pouches of all time. It does show everything off, I mean everything! It enhances what you have and make it look amazing. Luckily under the shorts, I wore it wasn’t too bad. Cocksox has consistently had some of the best construction over the years and this pair lives up to it.

Sizing for Cocksox has been consistent over the years. Before I would tell guys to go up a size but now it’s pretty spot on. Just follow the size chart and you won’t have an issue. I received an XL pair that fit pretty well. The waistband didn’t restrict. I hope I won’t be in that size much longer!

Overall this pair was awesome. The few issues I had were not noticeable. The pair held up to my wear and work out very well. I love the look and fit of the pair. The construction and fabric are always top notch. I highly recommend this pair.
