LIFETIME WARRANTY- This backpack is for any individual who is hard on the bottoms of their backpack. It is made of recycled car, tire bottom so virtually nothing can put a hole in it. This is a rare style as they don’t make it anymore and I was almost tempted to keep it because Jan sport was my first job out of college as a designer at the headquarters in Appleton, Wisconsin. This is a great bag for any person for school or travel.
