if this is a stock unit that could be the likely cause, its not a perfect match to the shape of your head....if its a custom then perhaps your template was a bit faulty in design....additionally it could be an attachment issue......maybe you dont have the tape right up to the edge, perfectly lined up. sometimes you need to trim the tape......i use a perimeter bond and when i do the tape i make sure that each piece of tape is perfectly lined up to the edge and that each end does not overlap. swith some pieces i have to trim the edge of the tape at an angle. think of it like laying down a tile floor...trim the tape to fit the area to be covered and each piece perfectly trimmed to meet up with the next piece.

if it is a fit issue you might need to cut darts into the piece. a poster on here reubin shows how he does this and what they are.......in the mean time........put a bit of glue under that spot that is lifted....tie a headband around it till its stuck down good....and GET WITH THE HOT CHICK!!!
