Replacement cap
[This review was collected as part of a promotion.] The cap itself is fine, but I’m concerned the same problem with the threads will occur again. Hopefully this one will last longer.

Game changer
[This review was collected as part of a promotion.] Can run/walk while taking a chug/sip without having to stop or slow down and spill all over your face.

Needed it for shakes
[This review was collected as part of a promotion.] Drinking shakes with any other lid is super annoying- this one is perfect!

Wish there were colors
[This review was collected as part of a promotion.] I like it but it does clash with the rest of the water bottle. I wish this came in colors.

I love the size of the opening
[This review was collected as part of a promotion.] I bought two of these to replace the caps on two ThermoFlask bottles. I hated the small opening on them so I took a chance that these Hydro Flask caps would fit. They do. So, if you want to upgrade your drinking experience, these are great!

Wide Mouth Flex Chug Cap
[This review was collected as part of a promotion.] Very happy with my purchase! My old lid was no longer working for me. Even though I cleaned it frequently, after 8 years it was gross. I love the new cap & was happy to be able to get a replacement without having to replace the whole bottle.

New top needed
[This review was collected as part of a promotion.] I got my Hydro Flask as a gift a while ago as a gift, the original top wore out and you don’t have the exact replacement, but the wide mouth flex chug cap was the perfect replacement

Why can’t you use this cover with coffee? Does this mean you can’t wash it with warm water and soap?

Does this fit the 40 oz Wide Mouth

I have the 64 oz flask. You need to make an incorporated cup for it! Also, a rubber net outside, or even a side handle, would be nice. I can't hold it with 1 hand. The outside is too slippery as well as wide. But mainly a cup.
