Thanks to ZeroSweep design, this small but mighty chest pack is packed full of features and functionality. The main compartment easily holds two standard fly boxes. Two ZeroSweep™ retractor stations (great for nipper and floatant attachment), ambidextrous hemostat station, foam fly patch and tippet holder cover all your key accessories. ZS2 version now includes a molle modular attachment station allowing integration with ZS2 accessories. Two stretch mesh pockets round out the storage possibilities.
