Inspired by the needs of the U.S. fly-fishing team, the SwiftwaterZS 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™ retractor stations, two Zero Sweep™ tool sheaths and two Zero Sweep™ foam fly patch stations (includes on foam patch) round out this carry-all vest.
