I used one of those cheap fleece blankets the summer before last on a week-long kayak trip on the lower Colorado River. I don't know if it was a Coleman or not, but it has a full length zipper that converts it into a sleeping bag. It was hotter than a pistol during the days and we slept on top of the fleece, but in the wee hours it became cold enough to throw the thing over me and it kept me warm. It's a handy little robe.
