So I recall some folks had trouble keeping some UQs snug against their backs at extreme temps, due to shock cord not working well.
Was a solution ever found? A different type of elastic for really cold temps? At what temps have people started having trouble with the shock cord?
I never thought about this with the PeaPod, suspension cords are nylon plus the support provided by the full length Velcro closure helps hold things in place. But every thing else I have uses some form of shock cord. I have not had any trouble yet, but I don't want an unpleasant surprise, either.
