Hello, one-handed hydration.

More hydration for more fun with our leakproof, Flex Straw Cap. Our 21 oz Standard Mouth with Flex Straw Cap is just the right size for staying hydrated before, during and after activity. Beverages stay cold for 24 hours. The Flex Straw Cap is leakproof and makes it easy to sip on the move.

Hydroflask are so excited to be able to offer Australia a configured bottle !

Please note:  

This does mean that the way the bottle can be used will change due to the straw lid conditions of use.  Our straw lids are desgined to be used with Cold liquids only.

Storing of carbonated liquids in the configured bottle can create pressue build up and affect the straws abilty to remain leak proof.
