Far-ouef's thoughtful minimalism is thought-provoking indeed -- the more so with the accompanying super fotos of bike & landscape [http://www.thorncycles.co.uk/forums/index.php?topic=9921.0]
After lugging Too Much Weight on my Scandinavian safari in August/Sept (partly 'cos I was carry infrastructure for two people, myself and my daughter), I've started thinking about doing with less, and maybe doing more with less as a result...
A bivy sack & tent fly is one option, for sure. Even better, a b/sack with just a tarp -- my smaller Integral Designs tarp is just 400 gms, and I've found that a Raven makes an excellent prop. Outdoor Research offers a bivy sack weighing just 510 gms, so those two items together are less than a kilo. On the other hand, there is The Bug Question, and for a couple of hundred grams more than the bivy-and-tarp combination, TarpTent offers a one-person tent with bugproof inner. Black flies are not to be trifled with:

My Thermarest Ultra-Lite Pro shortie has been durable, comfortable and not very heavy, but it weighs about 750 gms and there's an intriguing possibility on the market, one which weighs less than half that:

Have also tracked down a couple of ultra-lightweight summer sleeping bags, which of course are also ultra-expensive (less
really is more, if anyone ever doubted it.)
Thanks for the info & advice, all -- lots of ideas to lighten up summer tours for sure.
