Thank's for the great advice.<br>The idea with the tarp is really good.<br>I also want another sleeping bag. Down feathers get cold when wet and the Ultralight bag is very sensitive against wind. The nylon is so porous that you are able to breath<br>through the layers. That's the opposite for lightwight. A light breeze of wind and I feel cold. I want to use the tarp only when the wind blows stronger. And so I will look for a more wind-resistant outer shell. The most bags, which I have seen, are very bulky and heavy. A tip for a good bag for -5 degree Celsius (thank's Tom, I forgot that we have metric system, aso.). The most test about lightwight sleeping bags are for down feather bags and no synthetics.<br><br>Dieter<br>Germany/Stuttgart
