The Xtreme Head Strap Mount has been designed for all GoPro and other action cameras, providing a great point of view catching all the action right up in front of you. The Head Strap features an anti-slip strip to ensure Xtreme comfort in any conditions. If you do plan on using the strap in water, make sure you run a tether off the strap onto a wetsuit, life-jacket, or any other suitable flotation device.
