I purchased this item for my daughter who needed a rolling backpack. I researched many brands and polled other moms at school. This item is absolutely the best out there. The price was great and I purchased the extended warranty. It is full replacement. If it wears, it will be replaced with no hassle. It is amazingly durable and lighweight canvas. This rolls so smooth and quiet. The wheels light up, making it easy to see us in the crosswalk on dark mornings. Not to mention it looks cool from a kid standpoint. Endless comments and referrals. Because it is a Jansport product, I have no worries. Highly reccommend.
