I will part with my 'like new' red torsolite for $50 shipped. I can't see a mark or stain on it. The weight is 9.35 oz. or 265 grams. Since I don't store it in the stuff sack, it would come without one.
I have had it for years, but don't remember ever using it since I have probably 6-7 pads (several of which I should probably sell as well).
