Do you sell the chug straw lid separately?

I had ordered a couple different 24oz pictured with chug lids, but I received straw lids. What I have eventually purchased was a 24 oz with both lids, to make sure I got the Chug lid! So ask your questions to make sure you’re getting the right product πŸ™‚

Can I purchase a replacement straw lid for the Thermoflask?

Yes. I just went through this for the 40oz Thermoflasks I purchased at Costco. The straw lids are not sold by ThermoFlask directly (on their website) but it is sold by their manufacturer, Takeya, for $10.

Is the 24oz small?

It’s about the size around of a 16 oz plastic bottle of soda, but taller. It fits in my cup holder of my car. Don’t think the larger one would. Since it keeps ice so well, I often refill it with water on the ice still in it. I don’t consider it small or large. Like Goldilocks said, It’s Just Right.

Reviews & Experience

Kyle B: Purchased this Thermo Flask 40 Oz and Reviewed that “Holds ice for 24 hours, but a little leaky at times from straw” Great bottle. It is very durable and holds ice for at least 24 hours. The straw is great and being able to switch between that and the “chug” top is a great option. The 40oz version I purchased doesn’t fit any cup holders which is a little frustrating, but has been great overall so far.
My only issue has been some leaking from the straw top when closed sometimes, but after pulling the straw off to clean it I surprisingly have no more issues.
