When I need to carry two bodies or one body with a lens and a long lens to switch back and forth (I don't do this but you might), Black Rapid offers two different options. The sport strap version where all the weight is one shoulder. I have this but don't use because it sits on a lipoma and puts a lot of pressure on it. I also have the Black Rapid Double Breathe Slim which I use quite often. That is what I have in the photo with this product.
