Waterproof materials are a must for your fishing backpack. You also want to check your pack for tool docking stations, lash points, D-rings, and accessory loops that can help you organize your equipment. Check out what straps come on the pack, and how you might carry water bottles, food, and clothing. Packs should be durable, and make sure to get the size that works for you and the amount of gear you want to carry. At Sportsman's Warehouse, we offer all kinds of fly fishing packs from trusted manufacturers such as Fishpond, Orvis, Umpqua, and Allen.
