Best flask ever!
Lovely color, keeps liquids cold for the whole day and I love the removable top. Great for earrings or medication.

Love it
I've gone through many flasks, some more sturdy that others, some more insulated than others. This one covered it all: sturdy, durable, and well insulated. My "trial" trip was to Uganda, where traveling the roads and going into the bush were all well served with this flask. (Not all my travels are as exotic)
