I have tried them all. This is by far the best line of bottles on the market. Put hot coffee in my bottle one night and left it in the fridge. Checked it in the AM and Steam came out of the bottle when I opened it! Amazing product.

Hydroflask is fantastic. It keeps things just as hot or cold as a really heavy duty thermos, but it has a much slimmer design and looks like a water bottle. 4 stars because mine makes a slightly annoying "clunking/rattling" sound. The insulation is still good, but hydroflask customer service says that happens to some bottles.

I use my HydroFlask at the gym and also take it when I go shopping. The water stays ice cold (ice cubes don't even melt) even when I leave it in my car for hours on hot hot summer days when shopping at the mall!

My favorite thing about this is that you can carry it all day and leave it in a hot car for hours and your water is still perfect. You learn quick that you don't need to fill it with ice because it never melts... Also, It doesn't sweat!!

This flask keeps my water cold! Even when I have left it in a hot car for hours on end. The ice really melts slowly. There are many times I have ice the next day. I liked the flask so much, I bought more than one.

As advertised! Bought it for a trip to Disney in August. I would fill it with ice and water at 8 am and the ice was sloshing around well into the afternoon with 90+ degree days and humidity. My water ran out before the ice melted.

Can't find a better product out there for this purpose. Just keep in mind it doesn't take impacts well. I dropped mine once on pavement from about four feet and it dented. I wasn't concerned so much with the dent, however, it didn't insulate any longer. Short of that, it's still a great product.

I use this water bottle every single day! I LOVE IT!!! I know I will always have ice-cold water to drink because this product does exactly what it says....retains the temperature! I have purchased a total of 13 bottles, different sizes for myself but mostly to give as gifts! Everyone comes back with the same response...THEY love it!! It is a little pricey, but it is totally worth it! Thank you to whomever created this awesome product!

Used this on a camping & hiking trip in 95 plus weather. Kept drink cold all day and over night. Pricey, but worked so well will get additional bottles for rest of family.

I was on a winter camping trip and everyone had a different insulated mugs. This was by far the best of all of them. All were filled with hot drinks in the morning, then we hiked 5 hours to the top of the mountain in the 5 degree F weather, and when we sat down to eat lunch, all the other thermoses were luke warm, but the tea in the Hydro flask was still piping hot. No one could believe it.

It seems to be fairly durable, and the loop on the cap is great for attaching it securely to gear. There were no problems with leaks. I will be taking it on all of my outdoor adventures in the future!
