## Questions & Answers

**Q: Would the 20oz size fit in a standard car cup holder?**
A: 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!

**Q: Where us this item manufactured?**
A: 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!

**Q: Can i get a lid without a straw?**
A: Search for spout lids

**Q: 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!**
A: 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.

### ⭐⭐⭐⭐⭐ OG best water bottle
*by C***T on October 23, 2025*

I absolutely love hydroflask. They have a double walled insulation system that is sealed with a glass bead rather than lead (like stanley or many other brands) making this water bottle the safest to use in terms of lead exposure and overall health. It is very easy to wash - can be hand washed or put in the dishwasher depending on your energy levels, laziness and overall preference. I only ever fill this with ice water so I can’t attest to how well it holds up to hot drinks, but I assume it holds very well considering it’s insulated stainless steel. When I fill this with ice water i’ll put about 8 square ice cubes and it will stay cold for 24+ hours i’m not even kidding. The fun color, stable consistent temperature make it so much easier for me to drink more water and make it fun! This water bottle is easy to take anywhere with you, because it has a handle attached to the screw on lid. It does not fit in cup holders as it is too wide. but regardless it’s great! Just throw it in your purse or put it in your car on the seat or floor and it’s ready to take on any adventure with you!
