It is a water bottle that has everything I could wish for. No more and no less:
It is very sturdy and lightweight.It is made of plastic, but it is BPA-free and does not give the water any taste.
I like the simple design: just a cylinder with a wide screw cap. There is no gasket, yet it is completely leak-proof.
The wide mouth makes it easy to clean.
It has markings in ounces and millilitres.
The lid is connected to the body with a strap, so you don’t have to worry about losing it when hanging over a cliff. I can also use the strap to carry the bottle or attach it to something.
My favourite is this jade green one.
