Lots of water!
- Gender: Male
- Familiarity: I've used it several times
This is great! It hold water for me all day with out refilling. The one thing i kinda dont like is that its a little bulky and can sometimes be ackward to hold or cary. My friends with smaller hands have to use both hand to hold it were its so wide, but other then that its great! I tested on how long it would keep water cold. I filled it up with ice water and set it in the sun at 10:30am and at 5:00pm still ice cold, and it was about 75-80 degrees that day. Im impressed!
