[This review was collected as part of a promotion.] The hydro flask is a good insulated water bottle. It keeps water cold for a long time. They are also good at taking care of customers.

[This review was collected as part of a promotion.] Bought cap to replace an old one that wasn’t getting suction. I really like that it comes apart for easy cleaning. A little annoying that in order to get good suction the flip up needs to be a specific position.

[This review was collected as part of a promotion.] Bought this cap to replace the standard cap on my bottle. It works great and gets the job done. It's not as heavy duty as the wide mouth versions but still works great

[This review was collected as part of a promotion.] Works great , much easier than taking off the top to get a drink
Belinda P.
[This review was collected as part of a promotion.] So far it’s been great. Was able to cut the straw to fit my bottle perfectly. Doesn’t leak and fits well on the bottle
[This review was collected as part of a promotion.] It's easier to use, and hopefully doesn't break as easily as the original style of lid.

I swapped to this flex straw cap and it’s made drinking from my bottle so much more convenient, especially when I’m on the move.

[This review was collected as part of a promotion.] This replaces the same cap that I had for 2 years. It was getting a bit yucky so I decided to replace it and ordered the same cap. The old cap never leaked but this new replacement cap does leak. I have done all the things, tried all the things and if my bottle gets sideways in my bag/backpack, it will leak. I will probably end up ordering a new cap and hopefully it won't have the same issue.

[This review was collected as part of a promotion.] I had two Hydro flasks, but only on flex straw cap, They're totally worth it, I had to have another!

[This review was collected as part of a promotion.] Appreciate the warranty replacement. Nice lid. Like that I don’t have to use the straw.

[This review was collected as part of a promotion.] Make no mistake— I have loved my Hydroflask purchases over the years: from water bottles and camp cups to thermo flasks for take and go: yet there is a VERY distinctive difference with my purchases of the last month: the water bottles now sweat— like big time perspire. They are sweating like glassware with ice— even with far less ice than I would fill my previously purchased (and much older) Hydroflasks. What’s going on?

[This review was collected as part of a promotion.] Way too small for my medium sized flask. Haven’t returned it yet as that is always a hassle.

[This review was collected as part of a promotion.] Perfect addition to my hydro fask. Like having the option of a straw or a traditional lid
Kimberly M.
[This review was collected as part of a promotion.] Decided to buy the Flex Straw Cap for my Wine Bottle that I use as a water bottle and this cap fits! Since the neck of the bottle is taller I did not need to trim the straw at all. Easy to use and easy to clean.
