## Questions & Answers

**Q: Re Hydro Flask 24", what does "flex lid" mean?**
A: no, you can't. if you watch the video it shows that you have to remove the lid to drink. i think the "flex" is in fact that the handle folds down, instead of being "fixed".  you can get a lid that has a pop-up straw.

**Q: Ok so does it come with little stickers?**
A: Hi - Wendy here from Tall Ridge, the exclusive authorized seller of Hydro Flask products on Amazon - Thank you for your inquiry! Our Hydro Flask products do not come with stickers. I hope that answers your question.

**Q: Curious... is the bottle supposed to be perfectly round all the way up and down?  i just received mine from amazon and it is not.  it feels oblong.**
A: Yes, it should be perfectly cylindrical (round) all the way up. If it's not, there is an issue, and I would think that the company would take care of it. To tell if it's in fact round, remove the cap, make sure it's empty, place it on its side on a flat surface, and roll it.

**Q: I just bought this hydroflask in the color olive. Is it normal for the lid to have to be forced to close all the way? It doesnt close easily**
A: How did this work out for you? I'm experiencing same problem? I know it's not normal as I have been using this brand for a couple years now. Did u keep and use?
