The default GoPro head bandage is awful. You won't film anything but shaking with it. Besides that, if you'll attach GoPro to your forehead and bend forward, the camera will capture only half of your body. For the full POV experience, you need your camera to capture the whole body.
Many extreme sportmen have realized that the bandage is crap and started to hold cameras in their mouths. That excludes the shaking and allows to film with the right angle. But you can't speak, you drool and your jaws hurt. A visit to the dentist costs more than the Adventure Mask.
Motorcycle, hockey , rugby and other helmets allow you to attach camera to the right spot. You can even install a heavy DSLR camera and accessoires to them. But unfortunately these helmets aren't designed for filming, thus you'll be uncomfortable with them. Also you can't film the stunts looking through the visor of heavy helmet
The Adventure Mask consists of hardwearing shockproof plastic and is able to withstand over 3 kg of weight.
All fasteners are made of light titan so you can not be afraid for your camera. Besides the mask itself doesn't weight much and sits tight on a face, due to this, the image isn't shaking.
