We made KAOS Weekend Bag because we needed a stylish bag with more compartments to get better organized when travelling with the kids. It has 1-3 flexible compartments, so you can choose. Double zipper opening and full access from the top lid as well. Mesh zipper on the inside lid for bits and pieces. 64 liter and hand luggage size. Carries as a backpack and is super comfy. The fabric is water repellent, durable, and made from recycled PET-bottles that come from consumer waste. It takes 24 plastic bottles to make enough fabric for one bag. So when you purchase a Weekend Bag you help prevent plastic from ending up in the landfills. For the good of tomorrow!
