The Umpqua Swiftwater ZS Tech Vest was designed for the needs of the U.S. fly-fishing team and hauls and organizes the most comprehensive stream assault like no other vest. Neck fatigue and forward creep created by heavy frontal fly box loads are eliminated with a fully cushioned waist belt and shoulder straps. This updated version now has two full-length, vertical zippers, accessing both left and right front compartments. This new design has almost double the storage and organization up front. The back compartment is now a full day-pack with 800 cubic inches of additional storage. Four Zero Sweep‰ă˘ retractor stations, two Zero Sweep‰ă˘ tool sheaths and two Zero Sweep‰ă˘ foam fly patch stations (includes on foam patch) round out this carry-all vest.
