Parents and parenting experts agree that one of the most important back-to-school purchases is the right backpack. According to Parenting magazine, to be sure you’re getting the right backpack it should include:

Two-Straps: Your child’s pack should have at least 2 straps. With kids‘ backpacks becoming more and more loaded with books and laptops, equal distribution of weight is key. There are also a lot of wheeled backpack options if that is what you and/or your child prefers.

Reflective: If your kids will be walking to and from school in lower-light situations, they absolutely need to have a backpack that has strips of reflective material. That way, they will be much more likely to be spotted by car headlights, bikers, etc.

Fit: Making sure the pack fits your child properly is very important. You want to be sure that the backpack is easily adjustable, enabling you to customize the fit, and easily change it as your child grows. Consumer reports say that the bottom of the bag should hit the child at the lower back. Additionally, it it shouldn’t be positioned more than 4 inches below their waistline, and the point on their body at which the bag and straps meet should be 1 to 2 inches below the top of their shoulders.

Weight: With so much attention on avoiding having kids lug overly heavy backpacks, most of today’s backpacks are fairly lightweight. But, it kind of defeats the purpose of “lightening their load” when you or your child overloads it with stuff. The Academy of Orthopedic Surgeons recommends that your child’s backpack not exceed 15 to 20 percent of a child’s body weight. But, the American Academy of Pediatrics is more conservative and recommends not exceeding 10 percent.

So, with all of this in mind, here are a few that experts consistently listed as top picks of 2017.

The JanSport SuperBreak (approx. $35)

This one’s been around for decades. Its hot selling point for elementary school kids is that it comes in over 50 different colors and prints, so there are plenty of ways they can express their individual style and personality.

Parents and kids that prefer more pockets for better organization might need to pass on this one because of the lack of pockets, but it’s surprisingly roomy, with plenty of space to fit a three-ring binder, notebooks, textbooks, school supplies and a lunch bag. Kids seem to love how light the SuperBreak is, and often comment on how comfortable and supportive the straps are.
