I have a bedroll I bought years ago, its a canvas bag (Like carhart pants) with a quilt, woool blanket and sheets in it, rolls up to about 12" in diameter and about 3' long.
Bought it from Herters about 40 years ago.. I think Cabelas sells them, prob Bass Pro as well.
I've slept form -40 to over 100 in it.. You just ditch the wool blanket and quilt if its too hot.
