Speaking of fleece, I thought of several methods, fleece jammies, fleece nightshirt, fleece sweat pants, none of which I liked in operation. But this year during my 2 1/2 months in AZ, I used a double-size fleece sheet folded in half to make the equivalent of a sleeping bag liner. That, plus a regular cotton sheet, and a light blanket worked fine in general down to 40F, below which I'd pull the sleeping bag over top. For clothing just a regular tee shirt. This rig was especially easy to get in and out of for the nightly trip to the bottle. (guy stuff).
