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. .

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

Size matters
[This review was collected as part of a promotion.] I purchased 2 of the 40oz Hydro Flask and love it and so does my husband. I hiked 5 miles last weekend in the desert and it was just enough to carry me through. I chose this company because they support SaveUSFS. org and they have excellent products.

Love our bottle!
[This review was collected as part of a promotion.] This is a perfect size for being out and about. We leave it in our car while doing errands or day trips and we know when we get back to the car we get to have a nice cool drink. It’s a bit heavy to carry with us at times (will have to think about getting the new micro sized ones). Love that Hydroflask thought of making small sized bottles with the same insulating properties. These bottles takes a beating cuz we use them nearly everyday and they hold up really well.

Great purchase
[This review was collected as part of a promotion.] I love the product. Keeps items cold for a long period of time even without adding ice. If the item is previously chilled. Would definitely purchase again
