I plan to basically live out of my backpack in the Yukon for four months next summer. Consequently, I am adding a few luxuries, which includes a comfortable, durable tent that protects me from mosquitoes, wind, and rain.
I have an untested theory that I would like to try. Basically, I'd make something in the shape of an ID silshelter, but only use silnylon for the portion of the roof that is actually above me. I would use 1.1oz DWR ripstop about 30" up the walls, and on the two "snouts" of the shelter. Theoretically, this would provide a spacious, wind resistant shelter that seals out the bugs (I'd leave some material as a sod flap), but has less problems with condensation.
Are there any problems I am overlooking here? It seems like something that somebody would have tried by now. I am aware that a mist will come through the DWR in a rainstorm, but I don't think it would reach me and the small area of my ground sheet, and will provide extra space to store some gear out of the actual downpour.
