HYDRO CELLStainless Steel Water Bottle w/Straw & Wide Mouth Lids (40oz 32oz 24oz 18oz) - Keeps Liquids Hot or Cold with Double Wall Vacuum Insulated Sweat Proof Sport Design teal/blue

Amazing! Tried for both hot and cold beverage. It stayed almost the same temp for 12 hours.

I live in the Middle East in Abu Dhabi and this waterbottle has been life changing! I put cold water into it and leave it in my car for a few hours and the water is miraculously still cold when I come back. It's AWESOME!I can't even tell you how hot the inside of my car must get ... the outside temp is over 100 so the inside temps must be at least 150F. And this waterbottle keeps drinks cold.My 8 year old takes it to school and is so happy he can enjoy cold water ALL DAY.I also love the straw cap. Wonderful, affordable product. Half the price of a YETI and works just as well. Hurray!

One of the best purchases I’ve done ever on Amazon. Really good quality and it keeps the water cool in Middle East summer

Awesome Product

Great water bottles!

As described, a bit bulky.

Great product, sturdy and good quality materials. Love the colour range also.

will keep your drink cool in 55 degrees C weather i am in the UAE and it works really well.

So the original packing was damaged when being delivered which left a tiny crack in the bottom of the flask. This meant that the vacuum was compromised and none of the liquids stayed cold for very long. After a few emails to the good people at Hydro Cell they were sending me a replacement. This one was VERY well packaged indeed.Great product, keeps things cold a long time even with the sports cap. Even longer with the other one. Haven't tried anything hot.

My low rating is because it looks like we were sent a filthy returned bottle. We bought two bottles. One came beautifully packaged, immaculate and they do look like great quality. The second came in no packaging but a baggie. I opened it to find it full of moisture and digustingness. Including the straw, e.t.c. I'd never let my child drink out of this. It looks like it came from a playground. I'm super disappointed in the choice this company made in sending us this. Now I have to pay out of pocket to send back to third party, even though they sent such a sub par item.

Because of the verbiage in Hydro Cell’s ad on Amazon, I thought my new, 22 oz flask would come equipped with a straw cap as well as the full cover. However, this was not the case and when I contacted Hydro Cell about it they immediately, (and I mean five seconds after I went to their website and posted my concern) assured me they’d be sending out a straw (Sports) cap today. I was so impressed by their customer service, as well as their beautiful and functional product, that to not give them five stars would have been a real crappy move. Dean was the person I spoke with and he was courteous and professional. I’ll be going back to Hydro Cell for their other flasks, for sure!

I love it it’s perfect

Awesome size and sturdy. Very durable. Only dislike is the smell when you first open it up. It has a smell like some coating has been put on the inside and it took numerous washes to finally get rid of the smell.9 months of use: I wanted to provide an update nine months later from when I purchase this… The plastic is almost ripped and a half so that is a disappointing. But overall, still going up to be a very good water bottle and keeping it cool.
