One of my least favorite things to do is repair a bladder in a kite. It's not that it is difficult it is just a pain in the arse. What makes it better is doing it with friends, for friends, and of course in STYLE wearing my changing towel.
Protect the fragile bladder of your kite by always gently landing it on a surface with out any sharp rocks, shells, or grasses, AAAAND always store your kites in a temperature controlled environment.
