I've got an Eddie Bauer polyfil sleeping bag that I grabbed from targets clearance racks for $3. The zipper had come unstitched on one side so a $23 markdown.
I've got some 2.5" grossgrain and intend to run channels down the long ends. But the question I have is : should I cut the bag in half? I see some guides suggest it, but I see other people just leave the bag intact.
I assume it's just a trade off between insulation and weight. It's suppose to be a 40* bag.
