I realised my sleeping bag and airbed were a) huge, b) heavy, and c) extremely old. I've just been to M*ll*ts where I bought smaller, lighter and phenomenally cheap replacements. Feel free to sneer at me for dropping off the bottom of the quality spectrum - these items are barely one-season, let alone 2 or 4.
Toyed with the idea of buying a gas burner and some cooking weapons (pots, cutlery etc), but I remembered just in time - I can't cook. Indoors or outdoors.
