Manna retro water bottle is the best. I'm on my third one. I only use it for water, cold water stays cold for hours . I sometimes leave mine in a car that is probably around 110 degrees ,for hours, and the water is still cold. It's durable and stream line , making it easy to travel with as it easily fits in the side of a backpack or in a travel bag. I got the tiger bottle, looks great, packaging is gift worthy Love!
