Have you heard of the new water bottle from Arrowhead? It's billed as an "eco-shape" bottle. The idea is that it uses 30 percent less plastic so it's environmentally friendly. Are you rolling your eyes right now along with me? Better idea: Ditch the plastic bottles for a Sigg, or another reusable bottle. My Sigg, in fact, would probably take a prominent place on my can't-live-without list. Really.
