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

Is the straw lid insulated?

Good question! The leak-proof straw lid will keep your drinks cold for up to 24 hours and hot for up to 12. It is not insulated.
