Made the cap adapter to use my GoPro session in IPSC shooting. My cap, a Helikon, is very comfortable with earmuffs but the bill is very curved so I made a support for that curvature. The camera adapter part is a borrow but I can't find the original for proper credit and gratitude. This thing, in this cap can take some abuse and keep filming, I've been shooting with it and the view angle can keep a good perspective without being in the way.
