SIMMS Headwaters Sling Pack
The SIMMS Headwaters Sling Pack is a premium fly fishing sling pack designed for anglers who demand professional organization, quick access to their equipment and maximum freedom of movement. Combining a durable construction with a dedicated fly-changing workstation, this pack provides an ideal solution for active anglers who spend long days on rivers, lakes and remote fishing locations.
Built from rugged 630D High-Density Oxford Nylon with a TPU-coated frontside and PU-coated backside, the Headwaters Sling Pack delivers excellent durability and resistance against demanding fishing conditions. The water-resistant YKK AquaGuard® zippers provide additional protection against rain, splashes and moisture.
With a practical 12-liter capacity, the pack offers enough space for fly boxes, leaders, tippets, tools, accessories, personal items and other essentials required for a full day of fly fishing. Its streamlined sling design provides excellent storage while keeping the angler mobile and unrestricted during casting and wading.
The key feature of the Headwaters Sling Pack is its integrated compression-molded workstation with a fly patch, creating a convenient mobile tying and fly-changing area directly at the water. This allows anglers to quickly replace patterns without searching through boxes or leaving the fishing position.
Behind the workstation is a practical magnetic closure pocket for quick access to frequently used accessories. The main compartment includes internal organization features, including beverage sleeves, while the side retractor docking station provides a convenient attachment point for nippers, forceps and other tools.
The ambidextrous design allows comfortable carrying for both left- and right-handed anglers. The adjustable shoulder strap and chest strap with side-release buckles provide secure positioning and easy on/off functionality during changing fishing situations.
A dedicated net holster sleeve located on the bottom of the pack allows convenient landing net storage, while additional webbing attachment points on the rear of the shoulder strap provide options for mounting frequently used accessories.
