How well do these keep beverages hot? Are they well insulated?

They keep beverages hot for a couple hours. Much longer than the paper or styrofoam coffee cups, but not as long as some of the really expensive ones. I find that I comfortably finish my drink while it's still hot.

I have no problem with hot beverages. The tablecloth is thick enough to handle them.

They are reasonably warm. They do retain moisture if your hands perspire. If you leave them in the car overnight, next morning they will be cold.

Very minimal insulation. I'd look at something different for hot drinks. I never tried hot drinks but it didnt keep cold ones very cold. It seems like nothing more than a big plastic container for liquids.

I understand your concern in regards to getting hot, but I believe you should be fine with these. I ran a half marathon in these and never got over-heated.

No, they don't. They are a great way to keep liquids cold for extended periods without sweating.

Sorry, I had to check with my husband, who takes these mugs with him on the road. He said, Yes, they do a good job of keeping liquids how/cold.

No, they aren't insulated. Camelbak does make insulated metal and plastic water bottles though.

Having never owned the stainless steel one I cannot compare them. But I can tell you that this model will keep hot beverages hot for at least 4 hours or so.

I know you can drink cold drinks, haven't tried hot- they are plastic- so I'm not 100% sure.

I do use these with hot beverages - actually tea and I don't find it a problem as it doesn't get any hotter than the beverage and if you are cautious when you initially use them until you become used to the difference and use common sense, you shouldn't have a problem.

I use them for espresso shots in my office - so in general they are only about half full. That being said I have not had any issues with them being too hot to hold.

I think they can withstand heat; just not from cold to hot. I think most glass is like that.

I have never tried this, but I do wash them in hot water and they are fine. I would say it would be safe as long as you run them under hot water first and be sure to get the inside and outside equally hot. I love them for cold drinks, because they don't sweat, and they keep the drink cold for a long time. I guess they must keep hot drinks warm for quite some time, too.

Yes & yes. I love thee glasses and the beverage stays cold for a good long time and even if the drink is warm, it will make it cold. I'm thinking of ordering another set. Best ones I've found for keeping liquids cold.

I put them in a gallon thermos jug for my husband to take to work and he said his water in the jug is cold almost the whole day and he's out in the FL sun and the jug is in the hot car all day. So I would say they stay cold for a good amount of time or at least in thermal thermos. I've never used them for anything else, just got tired of filling the ice cube trays nightly(don't have an ice maker) so he had ice to go in the thermos each day. Hope this helps.

I don't know if they are microwave safe, but I don't think these cups are appropriate for hot beverages. The cups are not insulated.
