Glue less patch kits can be a lifesaver when you run out of spare tubes on a ride. I've had the situation of having mystery flats on a ride & went through all my tubes. The glue less patch kit takes up so little space & can make the difference between getting home under your own power vs being stranded in the middle of no where. The mystery flats were caused by rim tape failure. Although the wheelset wasn't used as often, it was older & the rim tape had deteriorated due to age. Once I replaced the rim tape, no more flats. So if there is no evidence of glass or any other debris causing flats or snakebite marks....then inspect your rim tape carefully.
Just another caveat. If you do use glue less patches on a ride, be sure to replace it with a real patch after you get home. Glue less patches are only a temporary fix & are not meant as a long term fix because from my own experience they will eventually fail sooner than later.
