nice for carrying water for workouts

This was a good product to buy for my workouts at my gym. It takes a liter bottle of water. It has a closed twist top so when its closed and I knock over there are no spills to clean

nice liter bottle

I got this other color of lavender because it was my favourite color. It takes a liter of bottled water. I take it to the gym. The cap is tightly closed so there is no leakage

Keeps drinks really cold!!

These bottle is the best. It keeps my drinks cold for a really long time and is a good size. Even if it's in a hot room my drink in this bottle stays really cold. I've had others and this is my favorite so far. I only wish it had a straw!
