Yes! I have used these for cold as well as hot coffee and hot tea. Never any problem!

Based on descriptive data from the Lifefactory website, I wouldn't recommend it. While there is probably no danger of the glass cracking with hot water, it's designed for cold drink use.

I don't recommend put the hot water in this bottle. I prepare put warm or cold drink in it. It is good for hiking.

It keeps both hot and cold...depending on what the temp was when place into the bottle. I don't think they recommend "hot" because since there IS a straw attached ...you might burn yourself. I put drink with ice in at 8am and left in car and carry all over and by 8pm, little chips of ice still inside. For hot, i don't put in boiling...i put in lukewarm and it stays lukewarm for quite a few hours as well. i don't think the plastic parts should melt since the straw parts are made of silicon. I also dip straw parts in boiling water to sterilize and it stays perfectly fine (I got the foogo for my daughter and her straw gets really nasty with backwashes...gross) hope this helps It keeps both hot and cold...depending on what the temp was when place into the bottle.

No, it is made for hot tea to be drunk from it. Now if you go to extremes boiling hot to super cold or vice-versa most any glass will break.

I have never put warm beverages in mine personally but I am sure you could! Its pretty durable. I think warmer rather than scolding hot! The cup probably wouldn't keep the beverage warm for very long but would be able to take the heat for a short period.

I tried a hot beverage once but found out the whole cup gets hot making it difficult to hold. Wouldn't recommend it for hot beverages.

You can but I don't think drinking hot liquids would be a good idea because the chemicals might leach out, plus it smells horrible when heated . I would not recommend it for drinking mugs only for decorative ones.

I don't think so. First, it's very unsafe to shake and blend hot beverages - if spillage does occur, it'll splash everywhere and probably cause injury. Second, the directions that come with the bottle specifically say NOT to use with hot liquids.

if the water you put through is drinkable then there is no reason the hot water to be unsafe

Dear John, To be on the safe side I WOULD NOT fill the container with hot water. It's rubber and fairly soft, so I only fill it part way to protect yourself and/or others from being burned. Lee

I just bought this thermos and the instruction/care booklet said not to be used for hot liquids. Better to be safe than sorry and burned. Hope this helps.

Hot enough for me. I add 1 half & half and still find it not quite ready for safe drinking.

I don't believe so. It's a relatively light mug which is great for travel and it does do a good job as a heat capacitor for a good while. I've had drinks stay hot up to an hour. Depends on the environment. A great mug regardless.

not 100% sure, id think so. maybe not boiling hot. but coffee/hot chocolate/tea id think should be fine... I bought some for my wedding, plan on doing hot chocolate on a stick. so I sure hope it doesn't brake on anyone.

I use these bottles for hot tea all the time and have never had any problems. In the few years that I have owned these bottles, I have only ever lost one when I accidentally left the bottle full of water in the car overnight during an extremely cold winter night. I think that as long as you avoid extreme temperature changes you will be fine. You can always run the bottle under warm water first to warm it up. Also I never pour boiling water directly into the glass, but wait a minute or two.

Having made both straight shots and many milk drinks using the machines milk warmer and frother, I can say that each has been hot enough to almost burn, but not so hot that it damage your throat, as many seem to want. Drinking beverages over many years at too hot can damage even down to your gut, and greatly increase the chance of Esophageal Cancer. I have a relative who suffers from this condition because she likes her beverages HOT! The damage takes many years to become apparent, but when it does, it aint no fun.
