Would the 20oz size fit in a standard car cup holder?

Hello - Mina from Tall Ridge here - Thank you for your inquiry! Typically, the 20oz should fit in a standard car cup holder. The best way is to measure the diameter of your cup holder and compare it with the diameter of your Hydro Flask. The diameter of the 20oz Wide Mouth Hydro Flask measures 2.91in. I hope that helps!

Where us this item manufactured?

Hi Joan - Wendy from Tall Ridge here - Thank you for your inquiry! All of Hydro Flask's products are designed in Bend, Oregon, and manufactured ethically in China. I hope that is helpful!

Does the 20 oz size fit in a standard size car cup holder? I’m asking if it will fit without any sort of adaptor. Thank you!

I believe it’s going to fit, but check the measurements. The adapter is kinda a pain, it works, but my 40 oz wants to tip over anyways. My 20 oz Contingo bottle fits the car cup holder nicely, without problems. It’s just my 40 oz one and our Thermos that don’t.
