How do you know what size backpack to buy for your kids? my boys are 9 and 7 - both tall for their age, want to get the right size
This size shouldbe fine. I would not go much smaller for boy's that age. With any luck, you can get about 3 years use out of your average pack. Not sure the boys will appreciate a pack with the word "junior" on the back, but I guess it depends on the boys and whether they get teased. Kids can be tricky. Good luck!
