great bottles but...

First off I got turned on to these bottles a couple years ago while looking for a replacement of an aluminum SIGG type bottle for my wife. Worked so well, now the whole family uses them. Have 8 or 9 bottles of all sizes between us now. While washing up a new replacement for one lost at a swim meet last weekend I noticed "designed in Bend made in China" now on bottom. Still love the bottles but you get 1 star for becoming another SELL OUT to China made garbage. Shame on you.

I have purchased 3 of these now. I take one to hot yoga and use the other one at work. I like drinking cold water throughout the day as that is the ONLY way I will drink water. Do these really keep my water cold Hell yeah. I also have a 12oz I like to keep by my bed side for when I wake up parched in the middle of the night or in the morning. These Hydro Flasks have been a life saver.

Best Bottle I Have Ever Owned!

I got this bottle as a door prize at an event my band was playing. I put some hot cocoa in it, drank a little, and then tossed it in my bag, where I promptly forgot about it. Imagine my surprise when hours later, I opened it to find steaming hot chocolate still inside! Since then, I have used it to carry mixed drinks, which it kept cold for at least 12 hours, and hot tea and coffee to work every day. I had tea after lunch the other day that I made at 6:00 that morning, and it was still hot. The only problem I have with it, is that it leaks if I hang a tea bag out the top to let my tea brew. I guess it isn't threading properly with the tea bag string in the way. You have to get this sealed tightly to prevent leaks. The one I won is also orange, which I despise, but since the company clearly offers better choices, I can't fault them for that! =)

You'll never go back to using a normal water bottle or thermos again!

A fantastically insulated flask great for staying hydrated whether you're looking for something cold or warm. I bought mine to carry hot tea up to mountain summits where it usually gets quite chilly. Not only would my tea be piping hot 7 hours after filling the flask but I actually had to wait for it to cool down! The same goes for cold water; ice takes hours to melt. At one point I remember having ice cubes still in tact a full day after filling it up! Great product that I highly recommend to everyone.

Awesome Bottle

This bottle is awesome, I have left it in car for hours during Texas summer heat and the water was still very cold. I also love the fact that it does not sweat when you fill it with it ice cold water.
