Simms Tributary Sling Pack Bistre
The Simms Tributary Sling Pack Bistre is a compact and functional fly fishing sling pack designed for anglers who need quick access to their equipment, comfortable carrying and reliable protection during active fishing days. Its ergonomic over-the-shoulder design keeps essential gear organized while allowing the pack to be rotated easily to the front whenever immediate access is required.
Built from durable 630 Denier High-Density Oxford Nylon with a TPU-coated frontside and PU-coated backside, the Tributary Sling Pack offers excellent resistance against wear and changing outdoor conditions. This rugged construction makes it a reliable companion for river fishing, wading and everyday use beside the water.
With a compact but practical 9-liter capacity, the pack provides enough space for fly boxes, leaders, tippets, tools, personal essentials and other accessories needed for a full day of fishing. The improved shape and increased capacity provide an excellent balance between mobility and storage.
The front zippered drop-tray compartment works as a convenient organization area and features both internal and external Velcro® fly patch locations, allowing frequently used flies to remain immediately accessible. Two internal mesh pockets help keep small accessories organized and easy to find.
The large main compartment with a durable YKK® zipper provides additional storage space for larger items, while the side Hypalon® tool docking station and webbing loops on the shoulder strap offer practical attachment points for nippers, forceps and other frequently used tools.
For added convenience during long fishing sessions, the pack includes an underside stretch mesh pocket suitable for carrying a water bottle or a lightweight rain jacket. The padded mesh-lined shoulder strap with adjustable quick-release buckle provides comfortable and secure carrying throughout the day.
