Thanks, hutzelbein. I'm starting to think that having the ability to zip up into a bag may be very helpful for staying warm in my Ridgerunner in the shoulder seasons. I will also likely add a lightweight underquilt at some point. Btw, do you think adding an underquilt protector without an underquilt (just insulated pad + underquilt protector) would help much with blocking drafts from below/ends?
