The ChicoBag is my most recent great travel finds. I ordered it impulsively right before Nick & my last big trip (2 weeks in the Pacific Northwest). I wasn’t sure how much use it would get, but I it was only about $30 on Amazon so I figured it was worth a try. After using it on our trip I’m not sure how we ever survived without one. It’s so small and lightweight it can easily be thrown in luggage without taking up much weight or space. Also it folds into itself and becomes it’s own case (that can even be clipped the outside of your luggage). How handy is that? We used this almost every day of our trip. It’s the perfect light day pack. Instead of using a bulky carry on backpack for day tripping around, this is small, light, but fits everything we needed. We packed lunches several days in it, used it to store things we bought, and kept our hands free the whole time. We won’t be going on another trip without it.
