... as such, but the Fishpond chest pack does the job. Follow the link.

The pic doesn't show the neck strap, but it has the same kind of clips as the waist belt shown. If you attach both clips of the neck strap to the right side loop ( with the pack facing away from you ) and then slide your left arm through it after putting the neck strap around your neck, it works nicely as a slingpack.

You can move it back out of the way, to the left as far as you want, and it pretty much stays there. To use it, just pull it around front. If you are on the tall side, the neck strap might not be long enough. In that case, you should be able to get some webbing strap to modify the original.

P.S. These Fishpond chest packs are bulletproof. I got hundreds and hundreds of days out of my first one, and my current ( second ) one looks like it will last for a long, long time yet. Another advantage is that I can wear a Camelbak Rim Runner hydration pack when needed and still use the chest pack as a slingpack as described.
