This is large sized with several compartments.Beautiful design for horse lovers. Great quality.I had a rainbow YakPak that served me well for three years (7-9 grade), hauling around two 2 inch binders, 4-6 notebooks, and all the rest of my junk each time. When the bottom finally tore at the end of my freshman year, I was as devastated as you could be over a backpack. Once I was done with all 7 stages of backpack grief, I went looking for a new one for the rest of my highschool years and found this. I cow herd and trail ride weekly, so I was so happy when I found this backpack pattern. It fits all of my stuff with room to spare and is just as big as my totaled YakPak. I was worried about size and if it could put up with the rough and tumble of the high school life, but it's just as tough as my old friend YakPak. Its awesome because it kind of self organizes-- you can have binders and books in one flap, notebooks and papers in the other, with two water bottle holders and a front pouch. I really wish the pictures did both of them justice. Anyway, it's a great, strong backpack and the point is that I bet it can go the three years of crazy abuse that my other one did.I'm a 20 year old Junior in college and I was in need of a cute booksack. I found this one with the horse pattern and fell in love! I was a bit skeptical at first because all the reviews were for small children but this was supposed to be the largest so I took the chance. I'm glad I did! When I first got it I admit I expected it to be a bit bigger, but really it's the perfect size! It's very spacious on the inside with plenty of pockets and places to put things. I attached some pictures so you can see the inside. The second to biggest pocket is plenty big enough to fit my notebooks and such while the biggest compartment perfectly fits my 15" laptop! And you don't really feel it when its in the booksack either. The material is nice and should last a long time if you take care of it, though I will admit the zippers on the second largest pocket were a bit stiff at first, but its getting better the more I use it. If you're like someone my age or older or an older teenager, this booksack is great for you also and I'd highly recommend it!I looked at many backpacks for my eight-year-old granddaughter before deciding on this one. The print is fun and fabulous, but honestly, it's the size, capability and options that make this backpack the best--and right--choice for us! The front pocket is perfect for permission slips, crayons or whatever the kids need to grab quickest! There are two side pockets perfect for water bottles. The two larger inner pockets provide many options for fitting an extra change of clothes or books and notebooks galore. Sometimes it's hard to justify spending money on a backpack, but you definitely gt what you pay for. Other backpacks did not have the space or options that this one does and I decided that I would spend the money to get a bag my granddaughter adored and one that would last through that famous kid wear-and-tear and this backpack certainly fits the bill. Great quality and fair price.A little expensive for a backpack, but it seems to be sturdy and the print is just what my daughter wanted. She was happy to find a horse backpack that wasn't pink!I bought this by special request from my 6 year old. She absolutely LOVES this bag. It's big - could grow with her through college kind of big - but she loves the print and all of the pockets. It's everything she wanted. The material is solid and I especially like the side pockets for water bottles. We previously had the (slightly) smaller version of the 'horses in pink' print, which was also a great bag but the side pockets for water bottles blew out halfway through the school year. I'm not worried about that problem with this bag. Great value for a great bag!Cute backpack if it wasn't a strange yellow color. Looked more ivory or off-white, but was more of a 'cornmeal yellow' in person.Purchased for my middle school daughter and she couldn't be more pleased. She does not have lockers in her school so she carries all of her books, notebooks, etc to every class. In her words, "It has tons of space inside. It has different, spacious pockets in the inside. It includes a smaller pouch for storage of pencils/pens. It has two outside adjustable side pockets for water bottles etc." She said she receives compliments on how great it looks.Item is good for about 35$. Quality is fair for the price I paid. Bottom is not too thin like other backpacks that are more expensive but small for a mega backpack! The front pocket has nice compartments but the back is separated in 2 medium size pockets. Would have liked 1 bigger back to fit in more than 1 binder in there. The one we have now can fit a pair of shoes, a binder and the lunchbox wich is not the case with this bag so a little dissapointment for that. Overall nice print and padded back. Should not be advertised as a "mega" backpack by wildkin because it is standard size. In pictures I put 1 big zippered binder in one back compartment and 1 babywipes box in the other. Still had a little room and the front pocket is very practical so pleased with my purchase. Bought with matching lunchbox. Would be nice to have a matching pencil case. It will be a 5 star hit as a gift to a horse lover :)
