The best way to keep all your favorite flies and tools right in reach is a quality hip pack. When you’re wading through a river or hopping across rocks, you don’t want a lot of weight on your back to make things harder.
Patagonia hip packs are spacious enough to hold everything you need on the river, but small enough to be worn as you navigate tricky terrain or reel in fish without getting in the way. Patagonia even has waterproof options in case you need to chase a prize trout in the rain, or end up in the river right next to him.
