All Weather Space Blanket Over cover

[Miguel]

I used one overnight once and don't recall any condensation. I believe it's all about proper ventilation.

I'm going to do a real test with my Ridgerunner and Spindrift. I'm hearing reports of a 15 to 20 degree difference between inside and out. With that much difference I'm hoping I can get away with my WM 30 degree bag down to 20 or lower. That would be pretty sweet especially since my zero degree bag is synthetic and heavier than heck.

I have been thinking of trying a setup like this myself. I believe to have a real test you have to try it overnight. I would be really interested to hear the results if you do an extended test.

Everything I did was over night. not just for a few hours. I even opened all the windows in the shed to get it as cold as I could. That was why I had a thermometer sensor in hammock and and in the floor.

Was thinking of using one on my HH also.

I've done the same thing with what I guess is a larger space blanket on a trip just below freezing (and damp). Leaving some room at the top for ventilation I still had some condensation dripping (thankfully I was using a synthetic sleeping bag). Did make it warmer though.

I've contemplated using one over top of a fleece blanket - slightly more insulation and to catch any condensation but now that I have proper winter rated insulation on the way I might just go with a light overcover.

I like the idea of the asym pitch.

I tried the asym pitch using an emergency space blanket and it worked pretty well.

I just made an asym over-cover from 1.9 oz/yd ripstop.

I cut the fabric trapezoidally, adding about 8 inches to the each of draping corners.

I then pulled the points that will attach to my ridgeline tight, and using tailors chalk I marked the angle of the ridgeline on each corner. I sewed...err ummm...I fastened with my thread injector, grosgrain tie-out loops, matching the angle of the chalk line.

I then suspended the ridgeline ends and pull the other corners down and out and made chalk lines to get the angle for the loops that I will anchor to the ground.

Pictures to follow.
