Certain sling packs can hold fly fishing rods or rod tubes. It is more common for packs to have rod tube straps to carry an unrigged rod on long hikes. This is a great option for anglers trekking to remote streams to keep your rod protected until you arrive. Other packs have elastic straps that can double as rod holders. On these packs, a broken-down rod without the tube can be secured until you reach your spot.
