Simms Tributary Sling Pack

Stay organized and ready for anything on the river with the Simms Tributary Sling Pack, updated for 2026 with more durable materials, improved water resistance, and a refined shape that increases storage while maintaining a compact, easy-to-wear design. Built for anglers who want quick access to gear without the bulk of a full pack, this over-the-shoulder sling keeps your flies, tools, and essentials within easy reach all day long.

Constructed from 630D high-density Oxford nylon with TPU and PU coatings, the Tributary Sling Pack is designed to stand up to wet environments, rough banks, and years of hard use. The ergonomic sling design rotates easily from back to front, giving you fast access to fly boxes, leaders, tools, and accessories without taking the pack off.

A YKK® zippered front drop-tray pocket includes internal and external Velcro® fly patch locations, making it easy to stage flies while changing rigs. The spacious main storage compartment holds larger fly boxes, tippet, and extra layers, while internal mesh pockets keep smaller gear organized. A Hypalon tool docking station, webbing attachment points, and an underside mesh pocket for a water bottle or packable rain jacket round out a design built for efficient days on the water.

Comfort features include a padded, mesh-lined shoulder strap with a quick-release buckle that allows easy adjustment and a secure fit whether you’re hiking to a remote stream or wading your favorite run.

The Simms Tributary Sling Pack is a reliable, streamlined storage solution for trout anglers who want lightweight organization, quick access to gear, and dependable durability on every trip.
