Review: A MUst have for hydration! - Love my Hydro flask! The color is perfect for my never ending sticker collection as I travel. Very durable and comfortable when hooked to a carabiner on the backpack. Liquid remains cold for well over 8 hours. Thus is a great gif idea!
Review: Great water bottle - I would recommend this water bottle as it keeps water cool. The earlier water bottles would not keep the water cold. On hot days, the water would get warm and the bottle would start stinking. Then it becomes very hard to remove the smell. I was skeptical on hydro flask and thought it was a hype. But now after buying this, I am hooked. Sometimes the brand products matter. The color is also very pleasing. It hasn't peeled so far. The other bottles, the paint peels.

## 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?
