wool, cotton, and maybe down sleeping bags?
i'm going to be using this for at home actually, as my apartment is small and i've become fond of sleeping on the floor (seriously). i'm needing something warmer as electricity is WAY too expensive and i intend to do without. i'd prefer something made of wool if possible. i read that it repels water better than down and cotton. a water proof outer would be nice though.
any suggestions on what to get for cheap? (less than $100)
