Today was the first day I put on any appreciable distance in the bush with this new Boonie Packer sling. And it was awesome! Basically it allows you to wear your rifle the same way as a guitar strap, with the added advantages of being able to quickly raise your rifle to firing position, alleviating the pressure on a single shoulder as opposed to a conventional sling, freeing up both hands for other tasks, and giving you great control of muzzle direction while walking. It even worked out great while wearing a backpack with a hydration pack/water line.

You can get the custom swivels and the sling on Amazon for about $100USD
