Love my Hydroflask
[This review was collected as part of a promotion.] I love it minus the straw. It gets kind of messy even though it’s supposed to be no spill…

My Everyday Water Bottle
[This review was collected as part of a promotion.] Dishwasher safe! This is the perfect size and capacity for an on-the-go water bottle. The straw is great and never has trouble with water flow. Love the color too.

40 oz
[This review was collected as part of a promotion.] the bottle is awkward. Wants to tip over. My son can’t stash it in his side pocket of his school backpack because it is too tall and top-heavy and will fall out of the bag. I prefer the 32 oz.

Great Product, Shipping not so much. . .
[This review was collected as part of a promotion.] The only purchase I'll ever make, this product is solid and has been my go-to HydroFlask replacing all the others. It's everything I've come to enjoy about HydroFlask. The only purchase because shipping and customer communication requires much improvement. I might buy HydroFlask at an alternate retailer, but never again from HydroFlask themselves. Learned a valuable lesson with this one.

Amazing!
[This review was collected as part of a promotion.] I love this bottle and take it everywhere. The ice doesn’t melt and it keeps my water cold. Also, love that it holds 40oz and still fits in a cup holder.

Hydroflask 40 oz
[This review was collected as part of a promotion.] It's such a beautiful color. Really convenient but just wish the water would stay cold longer.

Almost perfect
[This review was collected as part of a promotion.] I would give this Hydroflask a 5/5 but I'm only giving it 4 because the flip straw isn't as sturdy as I would prefer. It opens easily which is great but it almost feels flimsy when taking a drink. I prefer the flip straw to almost lock when you have it open but the easy opening is okay. Again, its more preference than anything otherwise 5/5

Don't stay cold or keep ice
[This review was collected as part of a promotion.] This thing does not keep ice or anything cold in it. It was pointless for me to buy these things. And I bought two, neither of them keep liquids cold for more than a couple hours.
