Those revolutionary folk at JOBY have released the all-new 3-Way Camera Strap, giving you a new dimension of flexibility and movement with your camera when shooting. Ergonomically optimized and lightweight, this system allows you to seamlessly transform from a wrist strap to a hands-free neck strap to a versatile shoulder strap in seconds. It is suitable for DSLRs and CSCs, and carries an incredible load-bearing capacity of 40kgs.

How It Works
Instructions from JOBY.com:
The 3-Way Camera Strap adjusts instantly with a simple pull.
To extend the strap, unlock the lock mechanism at the strap base and pull your camera and the strap in opposite directions. Then lock the strap back in place to secure in neck or shoulder mode.
To return to wrist mode, unlock the lock mechanism and the strap will automatically retract.
