These are one of my favorite green discoveries.  ChicoBags (www.chicobag.com) come in a rainbow of colors, are lightweight and incredibly clever.  They compress into their own teensy self-contained pouch and have a carabineer clip so you can snap them right onto your key ring.  No more forgetting them at home or in the car!  They pop into a pocket or purse, clip to a belt loop or backpack strap, or simply fit in the palm of your hand.  They’re especially great for trips to the Farmer’s Market.  Oh yeah, and celebs have them too.  Ed Begley, Jr., Leonardo DiCaprio, Steve Carell, Susan Sarandon, Hilary Swank, Gerard Butler, Patrick Dempsey, and many others all are hip to ChicoBags.  Begley even gave a testimonial on the company’s website.
