Everyone who is going to jump must have a signed liability waiver. If a jumper is under the age of 18, the parent or legal guardian of the minor must fill out the Sky Zone waiver. Waivers for birthdays and group reservations are only valid the day of the event and are not entered into our system. Once a Sky Zone waiver has been entered into the POS system, jumpers do not need to bring another waiver for a period of 1 year. However, previous jumps at Sky Zone do not ensure that your waiver will be on file.
