Updated with highly water-resistant materials and a refined shape with increased 9L capacity, this sling pack is your streamlined solution for moving light and fishing efficiently on PNW rivers.

Your gear stays protected whether you're wading deep, hiking through wet brush, or caught in a sudden downpour. PFAS compliant materials throughout.

Swing Forward, Stay Organized
The front drop-tray features YKK zippered access with internal and external Velcro fly patch locations plus two internal mesh pockets — perfect for organizing flies, tippet, and leaders. The 9L main compartment swallows lunch, extra layers, or a full day's worth of gear. Swing the pack from back to front in seconds for instant access without removing it — perfect for quick fly changes or grabbing your camera for that hero shot.
