The Imperial Cock Ring is .62 inches / 15.75 mm wide. But sometimes you just need more!
The guy pictured below is wearing THREE Imperials--for a total width of nearly two inches.
gear essentials' widest penis ring is .9 inches. We have talked about creating a wider style but realized that guys would rather stack them. Stacking really does make sense--you can easily get on THREE .62-inch wide cock rings but would have a very difficult time getting your balls through a two inch tube!
Stacking Imperial C Rings by gear essentials
So why stack? A lot of guys like the look (and when you are naked, it's a great way to 'accessorize'!) Some want to work on stretching their dicks. Many combined stacked cock rings with stacked ball stretchers. Regardless of the why, men do it because it makes them feel good. If it feels good, go for it!
