On sale due to a minor issue where some zip pulls (the things you pull on to operate to the zippers) are not correctly heat sealed and hence may fray over time. So we have decided to give you $5 off for the trouble and we suggest you watch this video for an easy fix or you can always buy zip pulls at camping stores or online. We are sorry about the inconvenience and this will be fixed on future runs so far though most customers report the fix is easy and not much trouble. Thank you for understanding.
