The Hydro Flask Straw Lid boasts a high-flow rate to quench thirst, and durability to withstand the most tenacious teeth. It’s top-rack dishwasher safe and has a convenient finger loop so you can clip your bottle when you’re on the go.
Please note that the Hydro Straw lid does not fit on the older style of Wide Mouth flasks. To find out whether this lid will fit your bottle, check the Wide Mouth Fit Guide .
Straw Cut Guide: Trim 2.5" off the straw for the 18oz wide, 1.5" for the 32oz, 1” for the 40oz, and just a hair for the 64 oz.
Please note that the Wide Mouth Straw Lid is not leak proof.
