I have an older Woods sleeping bag myself. It's down, and 44" wide.
When I moose hunted from a tent, it was the cats ass, even the year that the tent leaked and it got soaked, it was still warm. Now, as I've gotten old and soft, I hunt from a cabin. It's too hot. I sweat the early part of the night, and wake up with a damp sleeping bag when the fire is out in the stove. Solution of course is to leave the bag open when I go to bed, and I never zip it up.
Some years ago my well meaning wife decided to wash the bag. I've been trying to get the lumps out of it ever since. Fluffing it in a giant sized dryer at the laundromat helps a great deal.
What kutenay says above is really worth looking at.
My wife has a sleeping bag of only slightly smaller proportions, of the same age. Hers is filled with Dupont Hollowfill II. It never lumps, is machine washable, can be compressed to tiny proportions, and is apparently as warm as mine.
