Patagonia offers anglers a new option with the Hybrid Fly Fishing Pack Vest. The front stays true to fly fishing form with multiple drop in pockets and hemostat holders. From behind, this barely there vest looks like a daypack with a bungee strap. When you wearing this stunningly light and incredibly breathable vest, not only will you be more comfortable, but you can stay hydrated throughout the entirety of a multi hour fight with a fish. Nylon ripstop fabric on the outside won't fray from flies. Polyester 3D spacer mesh lining the vest helps you stay cool even when the pressure's on to catch something anything, really. Open sides add to breathability, in addition to leaving ample room for layering when angling in awful weather. The backpack element holds your hydration bladder, or an extra fly box and your lunch. A bungee strap on the pack holds your jacket in place. If you've not settled on a favorite rod, you can bring along an extra with the rod holder in the rear.
