Poor packing
Got 2 flasks during the Target week. The 2 flasks were placed side by side without any wrap whatsoever but the packing paper was just placed on top to prevent movement inside the box. Unfortunately with the transit and delivery, the 2 flasks were rubbing against each other that the Indigo color rubbed off on the pink one. The scratched part of the indigo came off already good thing I was able to use the white eraser on the pink one. :(

I received this item damaged and with the wrong lid. They were all sold out and I could only receive a damaged item discount. That doesn’t account for the lid I will now have to buy with the straw because they sent me one without it!

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. .

Wide mouth with flex Straw cap.
[This review was collected as part of a promotion.] The insulation works really well. It keeps my drinks cold for hours, which is perfect for long days at work or when I’m out training. I haven’t had issues with leaking, and the lid design is secure while still being easy to open and close.

Beautiful color! I really like this water bottle
[This review was collected as part of a promotion.] We've used HydroFlask bottles for about 10 years and love this brand for its ease of cleaning and clean third-party test results for its stainless steel.

Leaks!!
This Hydroflask leaks like crazy. It’s too wide to fit in a cup holder, and it’ll leak water all over your car even when the lid is on tight and the straw is fully down. So frustrating.

Hydro Flask - Changed the size of the Font
[This review was collected as part of a promotion.] This is our 5th or so order and we always have these engraved for family members. Helpful so boys don't lose them. The prior font fit with the size of the water bottle and was honestly very nice and stood out. LOTS of compliments and made them easy to spot. The current font is super small and doesn't look right on a 40oz bottle. We were surprised and disappointed at the change, especially since the price has gone up. Quality of the Bottles is still great, but wouldn't pay the extra for engraving again.

Finally, a good one
[This review was collected as part of a promotion.] I am getting rid of my lesser water bottles. This one really does keep cold liquid cold and the hot ones hot. Great for my round of golf.

Keeps Water cool
[This review was collected as part of a promotion.] Not my first Hydroflask, but the drinking straw lid, the straw does not stay open unless you put your thumb on the spout while drinking, otherwise you suck in air. I like how the spout snaps down into the lid.
