From Andy Pugh
Feedback is puzzled by why anyone would want a duffel bag waterproof to a depth of 300 feet (3 May). It would be of immense use for holding exactly the items that Feedback suggests – the box of matches, sandwiches and change of underwear – for a cave-diver, who might reach an air-filled passage, and even need to camp, at an underground point highly inaccessible from their starting position. This inaccessibility is very much the point of the endeavour.
