I actually just checked their website with the facts on the warranty and it says if a piece of hardware like a zipper or buckle breaks, it saves them and the customer the trouble of sending the whole pack and they WILL REPLACE BUCKLES AND ZIPPERS UNDER THE WARRANTY AND JUST SEND YOU THE PART =] saves you the $3 that a dealer would charge, and you dont have to pay $20 to send thej pack back =]
