Have a GoPro? Me either... oh wait you said yes? Dang it, I think I might be the only person without one at this point haha. If you've ever gotten your hands on one, you understand how amazingly versatile these little suckers are. I love shooting film on my iPhone, but there are a few situations where I just simply wouldn't put my phone in. I feel like this little mount right here would be something GoPro themselves would eventually drop, but in the meantime Polar Pro Filters has decided to make it. The Strap mount is exactly what it sounds like, a mount for a strap. Just about any strap you may have on your body(back pack, camelbak, life jacket, et cetera).
