Just wanted to share my two favorite water bottles in the world:
I first bought the Sigg bottle (with a different design) years back when they were first becoming popular. Although mine is dented and scratched, it still does me well!
A while ago, my mom bought me one of the glass bottles below and I fell in love! It has a wide top so it feels like you are just drinking from a cup. Ah-mazing! And I love that it doesn't feel like you are drinking from a metal bottle. PLUS, you can just throw it in the dishwasher (which I love because I am all about low-maintenance).
