I’m honestly sad I paid $30 for a TODDLERS waterproof backpack that isn’t fully waterproof with side pockets too small for any water cup… I love this backpack but…THE SIZE IS PERFECT, BUT NOT THE SIDE POCKETSThe shoulder straps are just wide and thick enough to not hurt their shoulders and stay on their shoulders(the clasp for extra security, and the emergency whistle as well? So cute), the backpack itself is just big enough to not tip my 2 year old over, the pockets on the side are sturdy but they are too small for a kids Contigo spill proof cup… maybe with some pull and use it’ll have some more give but at this point I very much struggle with putting a cup in the pockets and when I do I feel like it’s taking up an inch of space inside the backpack… which is quite frustrating given the smaller size of it.WATERPROOF? YES BUT ALSO NO….The outside fabric is absolutely waterproof but the zippers are not and neither is the inside layer making it only useful when MAYBE running in a light rain or dropping your backpack in a shallow puddle.. But if it is submerged into water, water WILL get inside the backpack and you will then have to dry the inside out before using it again. Since the inside layer is not waterproof, the layer will become soaked and need to dry out in order to not get the contents inside all wet as well…For this instance I do worry about spilled milk though!!Picture this: A milk cup spills in the backpack and now the clean up isn’t just a rinse and wipe down, it’s going to be tedious clean up AND DRY DOWN and now you have to find a new bag for your child tomorrow… because the liner is stained and soaked with milk…. again, how is this liner helpful? A $30 waterproof backpack, for a toddler, and the inside liner isn’t waterproof? One of the biggest disappointments in my opinion.AGAIN I LOVE THIS BACKPACK! I just wish they hadn’t been cheap about the inside liner and the zippers. Also, maybe made the pockets a bit wider for water cups to actually fit in?I love this backpack! The pattern is beautiful and I was pleasantly surprised at the durability and workmanship/stitching. The inside divider has been really nice to help seperate her items inside and it fits her matching lunchpal in there perfectly. It had 2 side mesh pockets which do fit smaller water bottles. It also has 2 outer zipper pouches, 1 bigger, 1 small. The zippers are easy to zip and durable. My daughter loves the strap buckle that makes it easier for a heavy backpack to stay put on her small frame. Her favorite part is the built in buckle whistle in case of an emergency. She knows she can't use it unless she's in trouble but she's tooted it for practice a couple times and likes to know it's there. Kudos Mibasies for thinking of/adding this safety feature.If we ever change up patterns I will definitely look for this brand again. Very impressed and was great price point for the quality I received.This book bag holds so much, I carry my son’s extra clothes, snacks and a yeti water bottle as well as my son’s water bottle in there. It’s the perfect size for a 2 year old and the straps are customizablePerfect size for my 3yo! The snap in the front makes it easy for her to wear even when it is full. It will not fit a pocket folder, though. I didn’t expect my 3yo to be bringing home a folder from daycare, but she does so keep that in mind. She wouldn’t be able to wear a bigger backpack, though, so I’m very happy with this one (we just fold the folder in half). I bought the matching lunch box, which turned out to be unnecessary since the front pocket of this backpack is insulated and large enough for her lunch.Got this for my 3yr old as her preschool bag /bookbag purse when we go out. It's so pretty and sturdy. Great quality! I'm going to order the big one too so she can have it for 4yr old kindergarten in August. I put her name on the front which made me love it even more. Buy it! I HAVE 0 COMPLAINTSSuper good quality! I love the two front pockets, the water bottle holders hold the kids contigo water bottle with ease. Zippers don’t get stuck. My 3 year old can open and close it easily! Perfect size for a 3 year old. We took ours on the aiplane, fit his tablet a couple toys and some snacks comfortably. And the material is easy to clean, I would feel comfortable throwing it in the washing machine if it got gross.These are great backpacks. I love the safety whistle too! They are sturdy/ good quality and padded so it won't hurt our LO's shoulders and back when loaded.7L fit our 3-4yo Pre-K LO perfect. It fit all his necessary classroom papers, change of clothes, water bottle, and of course, all his hotwheels and dinosaurs.12L was perfect for our 5-6yo Kinder. Large enough to fit standard folders, tablet, jacket, etc. Despite the school saying he needed a standard size backpack, I got this because all of the other kids were physically struggling to carry the standard size backpacks on her person's. I mean, the backpacks i saw were as large as the kid's themselves! We must do better mom and dads! We only got one back, so we need to care for it and there is no better time to start proper care them than at the start of their school careers!Love the design! Easy for my toddler to snap the buckle . And he loves the whistle !! It does fit a regular sized folder . His big lunch pal also fits in ! It’s perfect for his little body.En mi caso la utilizo como mini pañalera y el tamaño es ideal. Tiene muy buena calidad, y y está perfecta para una niña de preescolar.De muy buena calidad, solo los compartimentos de los lados no estiran mucho, deberás usar un termo para el agua no muy ancho.
