The LifeStraw Universal combines the dependable technology of the Original LifeStraw with an option to dependably seal most standard water vessels, including Hydroflask, Klean Kanteen, Camelbak, Nalgene and similar bottle brands (view the full compatibility list here). The LifeStraw technology lets you fill your water bottle straight out of lakes, streams, or rivers and filters bacteria, parasites, and chemicals from the water as you drink. The LifeStraw does not have a shelf life and is rated to filter up to 1,000 gallons (4,000 liters) of water, enough to survive for 5 years! Water bottle is NOT included.


1   Replaceable Filter
2   Cap sizes (narrow and wide mouth)
2   Standard sport mouth pieces
1   Leak-proof lid
