Great choice
[This review was collected as part of a promotion.] I got this to replace my 32 oz hydroflask and I love it! The extra size is very convenient and the tonal lid is a very nice touch. I would recommend to a friend every time!

Not the best water bottles
[This review was collected as part of a promotion.] I’m very disappointed in this product. Bought one for me and my daughter and when you use it it leaks down the front of you. .

Not great
[This review was collected as part of a promotion.] It looks great but the straw seems to draw in air half the time leaving a poor experience. Must be why it was half off
