Great size for 5 year olds!
Color: Disney: Frozen Elsa's Snowflake, Style: Kids Medium
This is a darling backpack. My daughter has been using it for a few months already and it’s pretty sturdy. The size is excellent for 5 year olds. It took me a while to find a backpack small enough that would fit her lunch box.

Perfect for my three year old!
Color: Bluey: Sky, Style: Kids Medium, Color: Bluey: Sky, Style: Kids Medium
It was officially time to transition from a diaper bag to a big girl backpack!
And both my daughter and I love this backpack! It is perfect size for her and holds everything she needs for school. It’s perfect for everyday use. I think the price is fair for the quality and sturdiness! She is gonna be able to use this until kindergarten! I definitely recommend!

Good quality toddler backpack
Color: Disney: Pixar Mashup on Blue, Style: Kids Medium, Color: Disney: Pixar Mashup on Blue, Style: Kids Medium
Good size toddler backpack! My son is obsessed with every character on the backpack. We got matching water bottle and lunch box too so everything is coordinated for daycare. Been using for 8 months now with no issues. Very durable. All zippers intact and work with ease.

Couldn't be better!
Size: Large
Yes, these are "old lady" boxers, but you can't beat the comfort and the fact that they are all cotton with covered elastic.
I usually wear a 7 in Hanes, etc. Large (or ex lg if you want them looser) fit me fine. They looked small out of the package, and even smaller after washing, but still fit. Size up if you are unsure.
