In the first place, it wasn't particularly large, having the carrying capacity of a decent sized supermarket shopping bag. Secondly, it wasn't remotely waterproof or even water resistant. And thirdly, it attached to the yoke of the webbing via four poxy straps with hooks on the end, rather than having its own shoulder straps. Aha! Suspected it all along, nice to have it confirmed. The whole human race? Perhaps in the mists of time, could the British Army have ever done anything to deserve this? I do know that the Irish Army were inordinately fond of the bloody thing for some reason or other.
