This is a great dual purpose addition to your travel kit. Since I tend to frequent the same cities over and over again I try to forgo restaurants for the fresh produce section of the local grocery store. I keep my bar fridge stocked with fresh fruits, yogurts and fruit juice; basically I try to eat the healthy foods I would eat at home while still sampling local cuisine. This produce bag is a perfect way to hit the produce aisle while serving as a dirty laundry bag on the trip home. The small size (9″ by 12″) holds a bunch of green beans, 4 oranges or 6 lemons. Big size (12″ by 16″) is just right for a head of lettuce, a dozen apples, a bunch of bananas or some kale. 100% nylon mesh. Machine washable.
