Head Strap 2.0 has a modular design that can be configured into three different setups. Use the headband with the top strap for more support and stability during intense activities, or the headband on its own for a low-profile setup during lower-intensity activities. The removable clip attaches your GoPro to caps, belts and more, while the main headband can strap your GoPro to stationary objects for added versatility. GoPro Head Strap 2.0 | Christy Sports
