## Description

From the manufacturer S26 Hydro Flask Launch

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.
Review: Fits perfectly - Great Fits perfectly and the spare straw was a great bonus

## Questions & Answers

**Q: Is this comparable with a wide mouth nalgene?**
A: I would say the only thing it is compatible with is a trash can.

**Q: Does this fit the 18 oz hydroflask bottle?**
A: No it will fit any wide mouth bottles though- I assume the 18oz is a standard mouth bottle, they do make a flex straw lid for smaller bottles

**Q: Is the straw long enough for the 40 ounce bottle?**
A: Yes! The straw comes extra long, and you use a ruler included on the packaging to cut it to the various water bottle sizes. Tip: cut it at a 45 degree angle instead of straight across for better performance!

**Q: Does this fit the 32 oz trail series m?**
A: If it’s a wide mouth bottle and straw lid is wide mouth yes
