  • Replace lost cap
Style: Flex Cap Color: Stainless Steel
Description in the write up made it easy to match replacement top with an existing hydro flask. Fits perfectly, works as described, no leaks!

  • A cute customization for your water bottle!
Style: Flex Cap Color: Stainless Steel
I bought this for my boyfriend and not only does he like the look, but it makes it so easy to distinguish! It’s super sturdy and a bit heavier, so maybe not the best for long hikes with the added weight, but for every day it’s super functional.

  • Quite satisfied
Style: Flex Cap Color: Stainless Steel
I received it on the 6th of July and so far there's no leaks but you need to close it properly, although there is a squeaking sound every time you close it. IT's worth mentioning that I'm using it only with cold water.

  • Excellent Lid.

Excellent material, well build, recommended.

  • Yikes! Damages bottle
Style: Flex Cap Color: Stainless Steel
The grinding steel-on-steel when tightening this lid damages the threads of the bottle, creating metal powder on the drinking surface which will be consumed with the water. This product should not be sold.

  • Definitely not fake
Style: Flex Cap Color: Stainless Steel
I was concerned about buying my new stainless steel flex cap online because of some reviews saying they got fake pieces sent to them. I am glad I ordered it. 100% legit hydro flask lid. Came in original packaging, fully labeled on the carrying handle as hydro flask. I put it on my bottle immediately and it looks great. Couldn’t be anymore happier with my purchase. ... show more
