Review: Perfect Cap for My Hydro Flask - I really like this Flex Cap. It fits my wide mouth Hydro Flask perfectly and feels super sturdy. I’ve carried it in my backpack and car cup holder, and not a single leak so far. It’s also really easy to clean, which I appreciate since I use my bottle every day. The stainless steel looks great and has that high-quality feel Hydro Flask is known for. If you need a solid replacement or just want a backup lid, this one’s worth it. Simple, durable, and completely leakproof.
Review: Great quality, useful new cap - I've been thinking of getting one of these caps for a while, and I'm glad I finally did. It's really encouraged me to drink more water now I don't have to undo and redo the cap every time. It sounds like a small issue but it makes a difference. The build quality is great as you would expect, absolutely no leaking. The size is a little larger than the basic cap height-wise, but there is no noticeable weight difference. Easy to clean as it comes apart easily. No metal parts so no need to worry about rust. I'd recommend for any Hydro Flask users who like to use straws.

## Questions & Answers

**Q: does it come with a straw?**
A: It comes with 2 straws.

**Q: My lid and straw combination only works about 60% of the time.  I'm only getting air even when the bottle is full.  Anyone else have this issue?**
A: Same issue, but i get air 100% of the time. There is no seal at all. I returned mine.

**Q: Has anyone else experienced a weird sucking or slurping noise when using this?**
A: Yes we ordered a two pack and one of them makes a horrible, slurping noise.  It is the most annoying thing ever. Are you switch the straw out and it is not the straw it must be the air intake valve on my lid.

**Q: does this fit the old style wide mouth hydroflask 32 and 40 oz?**
A: Hello, Miguel from Tall Ridge here! Yes, this is designed to fit both the newer versions as well as the older generations of wide-mouth bottles. I hope you find this helpful.
