The front pack has been nicknamed the Single Haul and is very useful worn on its own. It's an ideal minimalist pack that will hold large fly boxes vertically and a standard size bottle of water. The neck strap is needed to create a 3 point connection which allows the user to swivel the Single Haul from back to front and back again very easily. You can also substitute your stretch wader belt (shown above) in place of the one that comes with the Double Haul to avoid doubling up on belts.
