Water bottles to WOW! Recycled water bottles are used to make this eco-friendly bag. They are light weight and durable; holding up to 25 pounds. We love this bag because it is also water resistant and wipes clean especially with our vinyl letters for the personalizing. This bag is a good mid-size tote bag; we like to keep one in the car for all those times you need an extra hand. It works for the farmer's market, library books, knitting bag, gym shoes, groceries, the ideas keep coming.
