What owners and buyers said
Copied word for word, each beside the pick it is about.
A sizeable and well made flask with multiple drinking options. It's my favourite for a long day of sport. Keeps chilled all day and no signs of leaks.
Great quality flask that keeps hot for a very long time. Good solid construction with a sturdy handle so should last for years. It's not light weight.
it keeps water as hot ss when yiu put it in the flask because your not opening and closing the top every time you fancy a cuppa.
We use this to keep water hot for my sons formula whilst we are out of the house; the flask keeps the water hot all day.
