Question: Is the plasic BPA free?
Document: I was using a BPA free Nalgene bottle. Bought this for a rather large amount of money for a bottle...i guess i bought the hype as well.The problem with these things are the strap that connects the cap to the bottle.
I think this helped keep things colder even longer, but even on days I didn't refrigerate the bottle overnight, it still kept things cool for hours.The bottle is made of stainless steel so no worries about plastic chemicals leeching into your water when you leave it in a hot car. Any plastic on the bottle lid is BPA-free.
I really like this water bottle. It keeps drinks cold for a very long time. It is the right size to bring to work to drink out of throughout the day. Lid seals very tightly so I don't worry about it rolling around full on my car floor. BPA free lid. The only wish that I have is that it were dishwasher safe so I can deep clean it periodically.
I love this water bottle, I purchased it with the flip top lid and drink from it through out the day. I filled it half way up with ice and the rest with water and left it in my car for 9 hours, when I went to drink from it it was still very cold! I love that it is BPA free, I got the green and love the color. Yes it is on the pricey side but if I take it on trips etc.
No regrets. Great design, fit, and feel. My water is fresh, clean, and bpa free. I will be buying more of this item from Hydroforce.
Bpa free stainless steel5. Customer service. I broke the lid bc I was always bending it back. I emailed them and they replaced the lid right away. No questions asked.
7/10/14 - I have upgraded my review from 2 stars to 5 stars. I went to the Hydro Flask website and filled out their return form. Ends up my lid assembly was defective and they replaced it free of charge.
I live in Texas and yes, we struggle through some nasty hot days... But fill this puppy with ice and water and you're good for the whole afternoon! Local convenience stores will even let you refill with ice and water for free so I keep it in my car while I travel at all times...
This does exactly what they said it would. I think it keeps things cold for up to 10 hours or so. The bottle will begin to smell like whatever you're putting into it if you don't wash it very thoroughly. Even then it may not be scent free. I suggest getting a long handled scrubber to clean the insides if you're not using this for water. Great bottle!
Mine is still dent-free, but it has gotten a scratch from an encounter with a sharp metal corner. Nothing too severe, but it is there.Overall, I can't recommend Hydro Flasks enough. Living in the desert, being able to keep a good supply of ice-cold water is a Godsend, especially on those 120-degree days, and nothing does the job better than my Hydro Flasks!
