I love that this bottle is all black. It isn’t obnoxiously bright or colorful. I just want a simple, functional, reliable bottle. 

Pros: Clean, understated design. In the closed  position, it is fully waterproof. The nozzle can be locked. 

This is DOUBLE-WALLED SO IT WON’T SWEAT ON A HOT DAY WITH COLD LIQUIDS!

Cons: it is only suitable for cold liquids. You can’t store coffee, unfortunately.
