I have a claytor Jungle hammock and at old rag mountain quilt as well as a 3/8 inch closed cell pad. I was out in what I would say was 25 degree weather a couple of nights ago and although I slept a few hours I was pretty cold- especially at around 3 or 4am. I was dressed in full motorcycling gear with thermals on the legs and 2 jackets on.
To ameliorate this cold I am looking for an underquilt although I have to say I was a little cold on top as the old rag mtn shifted around. I am 6'4" and 200lb. I need something that will work in all 4 seasons. Weight is unimportant but bulk is as I am on a bike.
What does the doctor order for a situation like this ?? And what are the pros and cons, Spear stuff looks good but no need to restrict your answer to these items.
