Baseball stitch works well on an aire as the outer shell just protects the bladder which holds air
On the MFS trip that my NRS cat tore, we didnt have the time or experience to attempt an inside patch. The tear extended about an inch from the bottom seam where the gray meets the black and were concerned we didnt have the recommended 2" around the tear.
We did have a doctor and his stitch kit with surgical string. He did a beautiful job but it wasnt perfect and wouldnt lay perfectly flat. We were able to get a good patch over it (with about 1" overlap) and it held. Note: We did a second patch that then spanned the patch to the black material as they were both at the same elevation after the first patch was applied
I doubt if someone without his skill could do as good a job
Hey, if you want me to take a dump in a box and mark it "guaranteed", I will. I got spare time.
