Sleeping bag when backpacking or it's really cold, otherwise sheets, cotton blankets in summer and wool in winter, sleeping bag opened up to make a duvet, some combination of all of the above- it all depends on where I'm going and the weather. There's always a Mexican blanket or surplus wool blanket in my truck year round. I'm broad through the chest and shoulders (and unfortunately a bit more through the middle as I've gotten older), have big feet, a side sleeper and I move around a lot in my sleep so I hate mummy bags even though I own a couple. I miss my old school green canvas Coleman rectangular bag with the wool blended whatever it was for insulation and the red checkered flannel lining. Always comfortable to climb into, roomy, made a great floor covering to sit or lounge on in the back of the truck or tent and apparently tasty to one of the dogs I used to have. I wish I could find something similar- anyone know anything about the Cabela's bags? I hate Bass Pro and what they've done to Cabela's brands.....
