  • Simply fill the MyBottle from a tap or a lake, screw the cap on and start sipping; inner microfilter eliminates bacteria and protozoa

  • Carbon pre- and post-filter improves the taste of stale, swampy water
  • Bottle filters up to 26 gal. (100 liters) of water before it is necessary to replace the filter cartridge; replacement filter cartridges are sold separately

  • Flip-up mouthpiece is easy to access
  • Integrated loop on cap lets you clip the bottle to a pack strap with an accessory carabiner, not included
  • Bottle fits in bike bottle holders and most waistbelt bottle carriers
  • Remove the filter cartridge and attach the included straw to use the Katadyn MyBottle as a standard water bottle when filtration isn't required
