Am I able to buy any of the bottles that already have the flex straw lid on them or do I have to buy that lid separately?

You are able to buy bottles that already come with a flex Straw cap, but for the availability of those units, you need to check with a dealer directly. Your Hydro Flask team.

Why does it state flex cap as being ‘girls’?

No idea. This came with a twist cap and it is fine. I use sports bottles with different caps for when in the gym etc. The hydroflask is a really solid design.

What diameter is the base

Hello, The diameter of both the 18 Ounce and 21 ounce Standard mouth bottle is 2.87 Inches or 7.29 centimetres.
