Does not keep cold, not even indoors. Ice melts in hours. But, at least water doesn't leak.

[This review was collected as part of a promotion.] These are great little water bottles. I like that it comes with two options for lids to drink from. I tested them by leaving one in my car (Florida) and one in my house, both with ice in them. They both did well overnight keeping the ice frozen and lasted into the day before it all melted. I think these are a great addition for a water bottles

[This review was collected as part of a promotion.] We have a couple kids in sports and do they always need some solid sturdy water bottles and these are perfect. They keep drinks cold to last an entire day! I like having the option in the kids as well. They are very easy to clean out which is of the most importance.

[This review was collected as part of a promotion.] I absolutely love this bottle. It keeps water from the tap cold for so long.This bottle is a great size- it fits into the fairly narrow cupholder in my car. The different cup lids make it so easy to switch between using a sip and go straw when I wanna sip a cool, refreshing drink or screw on one of the easy use carry along lids. There’s been absolutely no leaks.

[This review was collected as part of a promotion.] I absolutely love these 2 water bottles! The 24oz is much more convenient as it's not too small or too big and these colors are simple but so cute. Water stays cold for so long and the built-in straw is so convenient for easy sips. Washing this bottle is super easy. The water bottle is leak-proof, keeps me hydrated, and is a super cute essential.

[This review was collected as part of a promotion.] I walk to work everyday and these are perfect for me to carry my water in my backpack. I love that it keeps things cold for 20 hours and that it is spill proof. It also does not have a plastic smell which a lot of these water bottles do. It is a great value and would highly recommend.
