I agree with what others have said about a Double Rainbow -- which I have and have used from Grand Canyon to Lake Superior. However . . .

Consider the Rainshadow 2. It is about the same weight as the Double Rainbow and a veritable palace. My son and his wife have the Rainshadow 2 and I was impressed enough to order one, myself. In fact, the box just came today. (Testimony to Henry's excellent customer service, I might add).
