Versatile Uses: The Pellking phone harness is perfect for skiing, fishing, cycling, motorcycling, and hands-free video commentary. We don't recommend using it for recording video while jumping and running; enabling your phone's anti-shake function will improve the filming effect. Excellent Choice for POV/VLOG: The phone can be positioned horizontally or vertically; the J-hook and long screw design allows the phone to rotate 90°. The strap is easily adjustable and fits over even the bulkiest winter jackets, accommodating a wide range of body sizes. Stable Structure: Features two non-slip rubber pads at the bottom and top of the phone holder. When you use the included mini wrench to secure the long screw to the J-hook mount, the phone clip will maintain your adjusted angle for stable shooting and prevent slipping. Quick Connection: The smartphone chest strap mount with J-HOOK allows you to easily install and remove your phone in just a second. It's incredibly convenient.
