Not as good as the recent FP deal but still decent for those that missed the deal last time.
Attach to the included 16-ounce reusable squeeze pouch to drink directly from the filter or squeeze water into a water bottle.
Screw onto most disposable water bottles.
Attach inline on a hydration pack — no adapters required.
Sip from the personal drinking straw and drink directly from the source, or scoop up a bottle of water directly from any freshwater lake, river, or stream.
