Fun scales design is one of the best I've seen in a long time. I've been looking for something this fun, that is comfortable to wear and carry, and has zero odour - here it is! A super lightweight backpack for dragon, dark mermaid or cool ninja fans, that fits the usual things like a laptop, along with a couple books and a sweater. I like that this holds its shape whether empty or full. There is comfortable, thick padding where the pack rests against the lumbar area, the shoulder blades, and on the straps. Shoulder straps can be connected with a cross body strap. Main zipper is a double zipper so you can open one side or the whole top (semi circle). It took a little warming up and zip unzip to loosen up the side zippers. Seams are sturdy inside and out. I love this MAdPAx scale backpack, and highly recommend it for kids of all ages!
