Packs and Vest for Fly FishingEvery angler needs a pack, vest, or bag to store their important fly fishing tackle. Anglers fishing short days that favor being lightweight often use a hip or lumbar pack. It's a fanny pack no matter what you want to call it. Anglers that fish longer days carrying lunch, jackets, or large cameras prefer sling packs or backpacks. If you are a boat fisherman or are looking to store large amounts of tackle should consider a kit bag.
