[This review was collected as part of a promotion.] This cap is durable and easy to use. Most caps will leak if turned upside down, but this doesn't. Great quality.

[This review was collected as part of a promotion.] Why cant you make a sipping top without all the plastic. This top spoils the taste of my ice tea.
Harvey B.
[This review was collected as part of a promotion.] Very good quality cap. Slightly disappointed in the flow of liquid through the straw compared to my previous pull-out style nozzle. You can't guzzle liquid for taking pills, etc.

[This review was collected as part of a promotion.] Great Addition to my HydroFlask water bottle. Easy to use and clean. Seals really good!
Hayden B.
[This review was collected as part of a promotion.] bought this because the carry strap on my old (standard) cap broke. it's been SO NICE to be able to drink water without fully unscrewing the bottle! my one issue is that the straws that come with this cap are a bit long for my bottle, so they're getting slightly bent, but they're not bending so much that they're unusable

[This review was collected as part of a promotion.] It’s difficult to drink out of, where the old type was much better. Quality is there, just not a Quality is there, just not a design I prefer. Any chance I can get one of the old type? Thank you enjoy your day.

[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.
Summer L.
[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
William T.
[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!
