Scuba Diving Accessory: Neoprene Mask Strap Cover (Slap Strap)
Designed for comfort, the neoprene cover helps eliminate hair tangles and tight strap discomfort on the head. It will also help most masks to float if you lose yours during your dive.
Once in place, the velcro seals tight along the side and there are also a couple of extra velcro patches inside to hold it in place on your strap.
Each strap comes in two colour schemes, just flip it over to change. Choices are: Aqua/Navy, Pink/Purple, Red/Black, Yellow/Royal.
