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 ZeroSweepTM retractor stations (great for nipper and floatant attachments), ambidextrous hemostat station, foam fly patch and tippet holder cover all your key accessories. ZS2 version no includes a molle modular attachment station allowing integration with ZS2 accessories. Two stretch mesh pockets round out the storage possibilities.
