SIMMS TRIBUTARY SLING PACK

Updated for 2026, the Simms Tributary Sling Pack is the ultimate streamlined solution for anglers who need quick access to their gear without the bulk of a full vest. Constructed from ultra-durable 630 Denier High-Density Oxford Nylon with a TPU-coated frontside, this pack is designed to shed water and withstand the rigors of heavy brush and rocky banks. The refined 9L shape provides increased capacity while remaining light and comfortable for all-day wear.

The Tributary Sling features a YKK® zippered front drop-tray that doubles as a mobile workstation, complete with internal and external Velcro® fly patch locations. Accessory management is effortless thanks to a Hypalon tool docking station and shoulder strap webbing loops for zingers or nippers. With a padded mesh-lined shoulder strap and a quick-release buckle, this pack ensures a comfortable fit and instant access to your large-capacity main storage.

Pro-Tip: The "drop-tray" design allows the front pocket to fold out flat, preventing your fly boxes from falling into the river while you're busy changing flies.
