From Peak Design:
Need to turn any backpack strap, belt or strap-like object into a mount for a GoPro® or any P.O.V. video device. Shoot video in ways you’ve never imagined with these durable and ultra-versatile products. Buy Capture and P.O.V. Kit together and save $5 off retail prices when purchased separately.
What you essentially have is a quick release system that allows you to attach your GoPro to belts and straps. I’m thinking it could be a great addition to my GoPro mount kit as it will allow me to securely fasten the GoPro to the shoulder strap of my PFD.
I have a set on order and expect it very shortly.
