I have a 15 degree Sierra Designs sleeping bag that I never use because it's too heavy and too warm at a 15 deg rating. Although it is the most comfortable sleeping bag I've ever used… It has stretchy thread between the baffles and the 600 FP down rest real cozy on the body. I'm curious about removing all the down from the bottom baffles since my sleeping pads don't require that I have any insulation on the bottom. Furthermore, I believe the baffles are continuous from top to bottom so I could remove some from the top as well and then re-sew the thing back. So, my question: Would removing all this down (say all the bottom and 10 percent from the top) even make the bag all that much lighter? Or at least light enough to keep me from wanting to replace the sleeping bag? The bag in question is the Sierra Designs Van Winkle Long weighing in at 3 lbs 12 oz! Probably would only get $30 or $40 if I were to try and sell it – right? Thoughts?
