Lots of stretch in these mesh briefs.
More than 10 years ago, I purchased mesh CX01 briefs, and they had no give in them, but these mesh briefs are completely different. Made from a very fine silk-like mesh fabric, they have plenty of stretch, so no need to go up a size, your usual Cocksox size will work. They are very low-rise, as with all the CX01, and have the original late 2000's pouch. I need some extra room up front and this pouch provides me with just enough. If you need less than average room, this pouch probably won't work for you, go for one of the other CX pouches.
The mesh feels fantastic to wear and is thinner and lighter than the standard Supplex material, great for summer wear. I would suggest making sure that you are waxed or shaved, as hair stubble doesn't work well against the smoothness of the material. I find the briefs stay in place all day and it feels like I'm naked despite having complete support. These are comfortable, sophisticated-looking briefs with more than a touch of sex appeal.
