JBL Hydro Seals size chart

JBL Hydro Seals ear plug sizing chart

JBL Spear Guns makes a great ear plug product to help protect surfers, swimmers and divers from surfer’s ear and swimmer’s ear.

The problem is that there is no simple chart that shows how you determine the actual size you need to buy – small, medium or large.

So what I’ve done here is include the actual sizing diagram included on the back of the product. Enjoy.
