Super durable and stylish looking
High quality backpack with multipurpose pockets. Zippers, clips and handles are great, durable material, high resistance to the dirt and moisture, love it in black color! It’s pretty pricey for a kid backpack but it is worth it. All stitches are in place after several months of hard use. Size and variety of pockets make it functional for different activities and weights! It’s perfect for Pokémon lovers, it fits giant folders with cards :)

Cute but larger than I thought
I did not look closely at the dimensions I don’t guess. It was a really cute bag but it was really big. I got it for my 4 year old and it is not the fun little bag it is a large backpack size. All of that being my fault, it is a great quality bag. The map is a pencil bag and really cute. It does separate completely and not connected with a string.

WOW!!! This is a Super High Quality THICK Heavy Duty Backpack Absolutely Not a Cheap Toy!!!!!!
This is a REAL FUNCTIONAL HIGH QUALITY HEAVY DUTY SUPER AWESOME VERY REAL I KNOW I SAID THAT ABSOLUTELY NOT A TOY OR COSPLAY ITEM backpack!! I bought this to wear for fun while riding a Honda Monkey Bike around town and was worried I was getting a toy/cosplay item that would not hold up to 40-50mph speeds on a minibike. Turns out, there is absolutely no problem with that cuz this thing is thick, padded, and super high quality. In fact, I would have no problem using this backpack on my full-sized sportbike going 90mph - I mean the legal speed limit - down the freeway. Heads up, this thing is pretty large, like it's absolutely wider and taller than your typical Jansport backpack everybody had in high school in the '80s. The interior is basically normal size cuz all that extra exterior dimension/size is basically heavy duty padding for the design of the shell and spikes which trust me bro are crazy heavy duty like I'm telling you I'm kinda shocked I was expecting a thin piece of junk that would rip apart after a couple washes or a handful of motorcycle rides, but I was 100% wrong-o. In case you are curious, the circumference of the spikes at the base are about the same size as your typical 500ml plastic water bottle and from the base to the point is almost exactly the length of your standard Bic lighter.

Very good.
Awesome backpack, arrived exactly as we expected. Purchased roughly 7 months ago and the material has held up very well. I read reviews that there wasn't much space, but I don't have that issue at all. Plenty of space for my child's day to day school needs.

It’s small but big enough for a 6 foot tall person to wear
It’s small and not easy to pack. But it does have some slots I added key rings and a chain link add on for adding or holding bags. But it is functional as a shield and even me being 6 feet tall it is very wearable. It lacks a lot of space and has no re-enforced straps. So I use it to go game shopping or run errands and simple things being the summer this was to replace my murse. If I was 12 I would love this more but at 44 it is good. If you don’t have a lot to carry to school then here is a good backpack. As an adult a good conversation starter and shows off my fandom for captain america. I use it for everything simple rather than that purse looking thing my family bought me. A good item in general all captain america fans should own it because you can put things inside it and hang it on the wall as a shield decoration. You add to the holes it already has to add attachments and when I find a good attaché addition I will re-enforce the straps since that’s the only place to put them. $30 on Amazon when I saw it at gamestop online $70 and not available so if you want it get it or risk the 3rd party ones that are questionable but acceptable go for it. Glad bio world made it and with text books you have a real defense item. Pleasantly surprised by it just had to get past my fear of looking childish. But between this and a purse looking thing I will take this. It’s officially my summer backpack for personal use. Winter is back to a giant black laptop bag or fancy backpack. I added another star for 2 reasons one I added Wynex attachments for the shoulder which added the extra storage I needed and second I was in a vehicle accident and it saved my upper torso from back injury and and protected my ipad from being damaged as well. A shoulder strap was not torn but damaged. I have to replace it but I had to add that on before I do. In addition to that a theory of bringing people together two electoral party is valid I get complemented for it by both sides which makes it easier to wear. I am very happy with it.

Cute pack
purchased for my granddaughter who absolutely LOVES this. It is generously sized and has adjustable straps. The map pencil case is adorable. It is well made with durable back pack material.
