I've used this bag twice a week for school for the past 8 months, and every single one of the cloth zipper pulls have unraveled/shredded. The more the pulls unravel, the more they are caught in the zippers. So I've had to cut them all of them off. The seams of the backpack are also coming unraveled such that 2-inch-long threads are hanging loose at seams all over the bag. Now I'm on Amazon shopping for a better quality backpack.UPDATE: High Sierra has a 100% satisfaction guarantee for their products. The claim was very easy to file and quickly processed. While they don't offer refunds, they did replace the bag and send a $10 rebate for future purchases. While this new bag does not seem to be of significantly different quality than the old one, HS should be commended for great customer service.
