💗I love SHO!!! I have almost every product and I have to say they do exactly what they say on the description. They stay hot (too hot😉) for the length of time stated so make a brew 3hrs before you want to drink it. I did have a small problem of the bottle lids getting warm and consequently heat loss but customer services replaced without hesitation or undue stress. I have had other flasks and insulated cups but none compare to SHO! I personally preferred the old style food flask due to its wider neck. Highly recommend SHO and they’re great grifts for avid adventurers.
