A combination of a traditional fishing vest and sling pack....for the best-of-both worlds solution. Patagonia's new Vest Front Sling features a vertical-pocket vest configuration on one side, with a larger storage pack (like the Stealth Atom Sling) on the other. Access to either is simple; just swing the side you want around to the front without having to take it off. External nylon utility keeper provides secure attachment point for zingers while a selection of easy-access pockets keeps the stuff you need handy.
Inside, there's a range of organizing pockets, a 100% waterproof, welded security pouch and enough room for lunch, jacket and extra fly boxes.
