In reply to CaelanB:
I have one of these, and imagine its great in warmer, drier climates, ** don't ** buy this for the UK. Lots of condensation as single skin (as expected), but as its a single unit (floor / sides etc), you can't separate it, so once wet (after most nights in the UK), you have to pack the whole thing damp/wet, and night 2 is always 'wet', so trying to keep a down sleeping bag, on a thermarest dry / away from the floor / sides is impossible. I've had quite a few damp trips with this tent in the UK. Get a light weight double skin tent. Free standing Big Agnes / MSR are much better
