We run on Mercury Outboards!
Sling packs have become extremely popular with wading anglers. Designed to carry what you need, they slide around to your back to stay out of your way when casting and stripping your line.
The over shoulder design gives you quick access to everything you need on the water without having to sacrifice the carrying capacity of a traditional backpack. Patagonia also offers waterproof options because you're going to be in the water...just sayin'.
