Give yourself options

[This review was collected as part of a promotion.] Buy your flask with the flex straw and add the flex cap to your order. Glad I have the flex cap option when I'm traveling or at work to take a break from my straw cap. Happy I made the choice to add this to my order.

The handle is not very robust.

[This review was collected as part of a promotion.] The handle of the cap broke within 2 weeks of using it. It is the second cap that we have used. This has not happened with our other hydro flask water bottle.

Great quality, fits well!

[This review was collected as part of a promotion.] Wanted to replace the top of my older hydroflask because the ring was getting gross and stained. I was worried this newer top wouldn’t fit, but it did! Seals well, no leaking

Possibly another replacement?

[This review was collected as part of a promotion.] It’s too tight. I have trouble unscrewing it. Is it possible to get a different one?
