Currently I use an REI Quarterdome T2 tent, which, despite the weight, I absolutely love. However, the footprint weighs 8 oz even. I'd like to protect the bottom of the tent, but since I'm carrying a few extra ounces with my shelter already, I need to shave a few ounces wherever else I can get away with it.
Here's my question. If I swap out the footprint for the same size piece of Tyvek, how much weight am I going to be saving? The footprint measures 78 x 46 inches.
Also, having never bought the stuff before, where do you get it? And do you have to buy a full roll or do the retailers cut it down for you?
Thx
