Hydroflask tumbler replacement straw FAQ

Does this fit all Hydroflask tumblers?

This page is for Koala Straw replacements made for Hydroflask tumblers in the listed sizes (20oz, 32oz, and 40oz). Make sure you select the size that matches your tumbler.

What’s the difference between Hydroflask tumbler and Hydroflask travel bottle straws?

Hydroflask tumbler and Hydroflask travel bottle lids use different straw lengths/fitments. If you have a Travel Bottle, use the dedicated Travel Bottle replacement straw page instead of this tumbler page.

How do I choose the right size?

Match the straw to your tumbler size (20oz, 32oz, or 40oz). If you’re unsure, check the size marking on your Hydroflask tumbler or compare your current straw to the product selection labels before ordering.

Is this straw plastic-free?

Yes. Koala Straw replacement straws on this page are stainless steel and designed as a plastic-free upgrade.

Can I use this in a different brand cup?

Fit depends on the lid design and straw length, not just the ounce size. For other brands, use the bottle finder page or the brand-specific replacement straw pages.
