I found this one at Walgreens for $16 it fits in most car cup holders keeps water with ice cold for 8-10 hours - you can even leave it in the car in 110 weather and come back to ice cold water. We have had 2 of these for 4 years still work great no leaks.
This larger one is $38 we use it for hikes and my daughter hooks one to her backpack. Worth every penny last forever.
