Hydro FlaskFlex Straw Cap for Standard Mouth - Leakproof - Honeycomb Insulated Cap with Flex Strap for Easy Carrying - Dishwasher Safe - Black

Q: Does this cap come with the straw?

No, and I would not recommend this product either. It leaks. Not fit for purpose.

Q: Will this lid fit a one green bottle or klean kanteen flask?

I don't know. I suspect they are brand specific so would need a Klean Kanteen lid for one of their flasks
