Review on GoPro Anti-Fog Inserts: Ensure Clear Vision with Official GoPro Accessory by Logan Tripp

A must for summer and underwater use! Pros - Many inserts included. - 1 liner should last all day as long as it doesn't get wet - Reusable (follow instructions) - Comes with an indicator that they're dry and usable - Comes in a zip pouch to keep them dry, why not use one Note Note that the lens portion of the body, the camera lens and the lens body are sealed when you get into the water, allowing the lens camera to fog up while the rest of the body doesn't. So it's useless for preventing camera lens fogging, but other than that it's great!
