The Umpqua Switch 600 ZS Sling is a simple yet genius design for a fly fishing sling pack. While many other slings are designed to only be worn on one shoulder, the Switch Sling is designed to be worn comfortably on either shoulder, allowing fly anglers versatility for their angling needs. The ZeroSweep garage port design protects small accessories from getting snagged by branches while bushwhacking through the backcountry, with the zinger attached on the inside of the pack and the cord runningthrough the garage door. The pliers sheaths feature a pinch tag in the center of each port to securely hold them in place. Each compartment offers excellent organization, thanks to the multiple mesh internal pockets and dividers, keeping fly boxes, tippet spools, and other accessories in place.
