Swell bottles keep you drinks cold for 24 hours and hot for 12 hours.
I fell in love with Swell bottles when I sent my children to school with them and they came home with empty water bottles. I could not believe they drank all of there water! But onceI tried it for myself, I understood why. It was because they had access to ice cold water, and they LOVED it!
They are great gifts for teachers, coworker's and friends.
The bottles don't sweat (no more water rings or wet spots on the desk) and the caps keep closed so nothing will leak into your purse or backpack!
Don't under estimate the value of staying hydrated, it keeps you focused, healthy and happy!
