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

The best brand in water bottles!
[This review was collected as part of a promotion.] Amazing water bottle. I’ve been using hydro flasks for over 10 years now and will continue to do so.

Perfect for indoor lap swimming
I swim 2-3x per week for about an hour at an indoor pool and I really needed a water bottle large to hold enough water for me to not need to get out of the pool to refill. This bottle has been perfect for that; I can fill up with cold water and it stays cold for the entire time (I was using an BPA-free plastic bottle and the water would get warm after a while) and the straw also helps with taking smaller pulls of water so that I don't overdrink either. Highly recommend

Son loves it
[This review was collected as part of a promotion.] My son loves it! He just wished he didn’t need the internal straw.
