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.

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 🙂

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. Www.takeyausa.com

Reviews & Experience

Mark J: Purchased this 40 Oz Thermo Flask and Reviewed that “This may be my perfect bottle” Easy to clean and fill. I put ice in my drink in the evening, and when I go to fill the bottle in the morning, there is still ice in it. When traveling on a plane, my previous bottle sprayed liquid everywhere if I opened it aloft because of the pressure differential. This one opens a tiny little vent hole at the top before connecting the straw, so the pressure is vented without causing a calamity. It’s sturdy, and I’ve washed it several times by hand and in the dishwasher without issue. Holds a goodly amount of liquid. And it cost significantly less than another brand (my wife bought one) that looks just like it. So what’s not to love?
