Katadyn Hiker PRO Replacement Cartridge
Katadyn Hiker PRO Replacement CartridgeThe Katadyn Hiker PRO Replacement Cartridge replaces scummy, microbe-laden cartridges for both the Hiker and the Hiker Pro microfilters. It's the same great cartridge that you get with your filter, but it's wrapped in a protective membrane to stay protected out in the field.
