Deuter SL Shoulder Strap Pack Accessories
The Vari-Quick shoulder strap harness on any regular Deuter backpack or child carrier can be replaced with the "VQ SL fit" harness, without problem, should the original harness not fit properly. Perhaps the padded straps are too long, too wide, or too far apart.

Reviews - Deuter SL Shoulder Strap Pack Accessories
I bought this not to support a back pack, but as support for my Nikon camera with heavy lens on front. Happy to say it worked great and took a load off my neck.
I bought these to attach to an older frame style back pack. they worked great. This was the perfect solution for what I needed. Very strong, distributes the weight perfectly, and fully adjustable.
