I love Notabag bags. I had two already, the recycled PET version, and was very happy with them. I keep them in my handbag and coat pocket, just in case I need to carry something, or want to convert the weight of my handbag to my back. I bought a new one, because one got lost and chose for the ripstop polyester this time. I am very pleased with the more luxurious material, because they straps don't fold and crease as much.
