[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.] Perfect addition to my hydro fask. Like having the option of a straw or a traditional lid

[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.

[This review was collected as part of a promotion.] Wasn’t clear that the lid came with straws so I bought extra straws and now I have 5 straws that are too long btw.

[This review was collected as part of a promotion.] Nice new design, but lacking the same flow volume of the older model.

[This review was collected as part of a promotion.] I love my new bigger Hydro flask bottle with my bright pink top… I always know where it is… And it holds a lot more liquid for when I’m out for a long day

[This review was collected as part of a promotion.] The new lids work perfectly and do not leak like the kids they replaced.
Michelle M.
[This review was collected as part of a promotion.] What's the point of sending me these? Customer retention is clearly not the goal. If so, you would offer to correct the issue from the beginning by acknowledging the lack of function in these caps. I won't risk buying the other bottles for kids knowing how poorly these work.
