Please note:

The way in which the Hydro Flask can be used will change due to the straw lids conditions of use. Our straw lids are designed to be used with cold liquids only.

Storing of carbonated liquids in this configured Hydro Flask can create pressure build up and affect the straws ability to remain leak proof.
