This was the perfect backpack for my kindergartner

This was the perfect backpack for my kindergartner. She wanted it pink, purple, with sparkles - this was the perfect fit. It's a great size too, big enough for all her homework and folders but its not hanging to her knees. She's using it in first grade this year, still looks brand new. Don't really use the cooler pocket for food, so I'm not sure how well it insulates.

I got this for my first grader, and it's the perfect size for her. Fits all school folders and big books comfortably. I didn't like the button that holds the  handles together since it gave the backpack a scrunched-up appearance, so I just trimmed it off. It seems really sturdy and hasn't gotten dirty really even though it's fabric. I'm really hoping I'll be able to wash it without it falling apart (once it does get dirty) since I want this bag to make it through a couple of years. My daughter does get compliments on it all the time.

We're very happy with this little kids backpack. It's sturdy and roomy. We like the padded shoulder stripes and the cute butterfly design also. It's perfect for a three year old little girl going to daycare. We can put a light jacket, a toy or book inside, plus her lunch box at the front pocket. I expect this bookbag to last through her grade school years.

My kindergarten son and i LOVE this backpack and lunch box. They are so bright and no one has a backpack like his. Just perfect for a kindegarten child. Perfect size!

This backpack is perfect for my 2.5 year old to bring to daycare. We put her diapers and wipes in the front pocket and her cup is held by those front straps and that leaves plenty of room for her blanket, change of clothes and stuffed animal in the main compartment. I got other backpacks on amazon that are smaller and fun for her to throw some toys in and carry around the house, but they didn't have the room needed for a days worth of stuff like you get with this backpack. Plus of the 3 backpacks I've got, I think this one is put together the best.

My daughter was gonna start preschool and I had been eyeing this backpack because she loves cats. It's a perfect size for her she is 2, and she loves it she puts it in her cubby and she gets it out and wants me to help her out it on when I pick her up.

My son is 3 and this backpack is the perfect size for him. It fits his lunch box and a book or two.  The side pockets are great for a water bottle too.

My 1st grader loves this backpack!  Seems quite sturdy to me.  I've checked the straps and so far, so good.  Zippers and side pockets seem durable.  Love the vibrant colors.  And the size is perfect for my 6 year old.  It's big enough for her folder, lunchbox, extra books and an occasional sweater inside and a bottle (or 2) in the side pockets yet still fits nicely on her back.  And she's very petite 6 year old.

This is the perfect backpack for school. My Daughter loves it, it is compact yet hold all her folders and all else that she needs. Sturdy and durable. Fabric is great too. This product shipped fast but most importantly my kid loves it.

This is the perfect size backpack for elementary school, maybe a little too big for preschool/toddlers. The quality is overall good and the print does not look cheap/faded. There are no interior pockets.

Long overdue review: my kid loved this backpack! It's a but small now for all his school books, but he still uses it on the weekends.

This lunch bag is great. My daughter is 3 1/2 and she already had the owl backpack from Skip Hop. When we enrolled her in preschool she was going to need to take her lunch every day, so I got this since it matched. It IS small, but that is what I wanted because she has to carry the backpack as well. It is perfect for her, but I knew exactly what I was ordering before we got it. My daughter is provided with milk at school so I knew I would not have to send a drink. If you need to send a drink, that may be an issue. The bag is very small. However, I was able to fit a Foogoo/Funtainer thermos across the bottom of the bag with a square Tupperware sandwich container in the top part just fine. This may or may not work depending on how much your child eats! I can put a half sandwich, cheese stick and apple slices in the Tupperware container for my child. That is enough for her, but you may not be able to fit a whole lunch in that size container. If you pack a thermos you could probably fit more in if you used plastic bags or snack bags since they are not rigid containers.

Pros:
-It is small enough for a preschooler without being too cumbersome
-It's very cute!
-Matches the bookbag
-Has a mesh bag inside for holding flatware and/or an ice pack (must be a flat, soft ice pack. not a hard ice block pack)
-label inside for writing child's name and phone number
-zipper goes all the way around the bottom curve so you can completely open the top and the flap will lay open flat, not stick up. Great for packing, it doesn't flop closed.
- The soft sides give a little so you can pack oddly shaped containers without damaging the lunch bag
-The handle on top has a clip so you can clip it to the backpack if necessary.
-Will fit several large rectangle shaped containers for packing bento-style lunches. Just use silicone cupcake liners to divide the inside of the container.

Cons you may notice(which were not an issue for me):
-Too small for a big eater or an older child.
-Will not hold a thermos AND a lunch, unless it is a small thermos and a container-free lunch (will fit a Funtainer and a "sandwich size" square container)
-No outer pouch for a drink or water bottle

For the price you can't beat it. It is an adorable lunch bag for a boy or girl. I can't speak for the durability since we just got it, but my daughter has been carrying the Skip Hop owl backpack for over a year now and it has held up wonderfully. When your child outgrows this as a lunch bag, it would make a great snack bag for outings.

This backpack is perfect for small kids. It's too small for school books but just the right size for hiking, My four year old loves carrying her own gear when hiking, so she was very excited to receive it. It's very lightweight and the straps size down enough to fit her just fine. It even has two pouches on the sides for water bottles along with two main compartments for food, spare clothes, toys ect. My only issue is that it doesn't have waist and chest strap. It seems to be pretty well made, so far it has has held up to being outdoors. Im considering waterproofing it for even better protection. Good backpack for the price.

My daughter loves this backpack.  She is only in kindergarten and it was perfect for that.  It is made from a light material but it lasted all year.  For the price I think this was a great value and was surprised that we completed a whole school year with one backpack.

I see most are talking about this backpack for preschoolers who only carry a couple of items. Well I'm here to provide a testimonial that it works for kindergarten school as well!

My little guy has been lugging around a backpack that's way too big and was always falling off his shoulders, no matter how much I tightened the straps. This backpack is lightweight with nice fat, secure shoulder straps that stay in place as they should!
The front pocket is nice and roomy, perfect for his lunch and snack containers and while a folder does NOT fit without bending under the smooth corners if one has a plastic bendable folder like mine this shouldn't be a problem. Folders put up with such abuse on a yearly basis anyway so a little dog-geared look won't hurt anything. ;)
The main section is also nice and roomy with lots of space for his change of clothes and all the things they send home with him - mainly art projects.

I really love the look of these bright colors and the rugged construction, it's so cute. I think this backpack will be perfect for my guy to finish out the school year and maybe even into 1st grade!

I was always looking for a backpack that wasn't bigger than my 5 year old, and this is the perfect one. My son loved it, and so did I. The picture displayed is exactly what you get, not like other sellers!

very nice backpack - I bought the light pink one (which has more kid appropriate pattern designs) - the quality seems to be good and sturdy. My daughter loved it and it is the perfect size for a young kindergartener or 1st grader.
