In reply to TobyA:
> Quasi-serious question: how can you not get on with plastic bags or drys bags in a rucksack? First, what is there to not get on with? And second, it feels verging on being unpatriotic - we're British. We pack things inside our rucksacks in waterproof bags because it rains and because that's what we've always done.
Yup absolutely. I've got a few small drybags that have set things in them that I can pack depending on what I'm going to do. Eg, one has headtorch, batteries, gaffer tape, tic tweezers, a wound dressing and a very compact bivvy bag and almost always goes in. Another one is a more complete first aid kit, another one has an emergency shelter and a blizzard blanket etc etc. Waterproofs, gear etc goes in loose. It makes it really easy to pack and to find things when I need to. If I'm with a group I can tell someone "look in the orange drybag" to find something specific.
