GoPro Anti-Fog Inserts (Hero4)

The GoPro Anti-Fog Inserts can be dropped into the sides of your GoPro camera housing to prevent fogging in cold weather and humid environments. Each insert can be reused approximately four times and you can dry them after use by placing them in the oven at 150°C for five minutes. The inserts should be stored in an airtight bag and they are compatible with all GoPro cameras.
