Thanks for Hydro Flask
I am a big fan of Hydro Flask. Water from Hydro Flask is really delicious because it doesn't smell like plastic bottles or plastic products.

So far, so good! I am crossing everything that this straw cap continues its purpose of making life easier and not leaking. I wish I had purchased these sooner!
