I’m married to a trainee bagpiper (and this is not a plea for sympathy).
Today’s invention is an attempt to make carrying the heavy pipes during a day-long event (eg Highland Games) somewhat less exhausting.
Three of the pipes would be specially strengthened and fitted with extendable carbon-fibre sheaths, with abrasion-resistant ends. They would emerge from the bag via a sturdy plate, to which they would be hinged.
During rest stops, pipers could invert their bags and sit on the plate, using the sheaths as the legs of a tripod stool.
