+ use this neoprene cover to protect your second stage against scratches and bumps. + attach it to the low pressure hose and wrap it around the second stage.
+ take it off with ease for every dive and your regulator won't be defenseless against misfortune on the surface. One order include one regulator protector. I dive with the cover on for my spared 2nd stage and it work just fine. But for your safety, i'll suggest you take it off before you dive.
This item is made of neoprene fabric.
