## Description

desertcart.com : Hydro Flask Water Bottle - Insulated Stainless Steel - Non Spill, Leakproof in 21 Oz Black : Sports & Outdoors

Review: Love hydroflask! Great quality even with daily use - My husband loves hydroflask and he needed one that seals well and travels easy. This worked perfectly. It fits in any cup holder we've encountered and the top hasn't leaks on him so far. It gets daily use so the lid quality seems good. The color is true to the photos. His water stays cold all day and even longer. The handle on the lid means he can comfortably attach it to his backpack too.
Review: Reliable Hydration Bottle - I’ve been using Hydroflask since the release. I believe it was 2009 when I purchased my first bottle. Hydroflask has gone through quite a few changes, design wise, changing ownership and adding products. It’s still my go-to hydration bottle. There are probably other bottles on the market equal to Hydroflask but it’s a brand I have found to be reliable. My water stays cold, it doesn’t leak and it can take an occasional drop. The 21oz fit easily into my bag and isn’t to heavy to carry if I’m holding it. I like the matte finish so it isn’t slippery in the hands. The lid quality is good and the handle is easy to grip and hold. A bottle brush fits easily into the bottle for cleaning and the “O” ring on the lid can be removed to scrub it and keep it from getting gross. Overall I highly recommended Hydroflask products.

## 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?

*by M***P on January 20, 2026*

Nicely packaged to prevent any denting. Water bottle is a nice color and will replace my 6 year old Hydro Flask. I love it that these bottles aren’t too heavy, yet they keep items nice and cold. They also are the perfect size for cup holders.
