For Sale is my Western Mountaineering Ultralight 20 degree bag, 6’6″ version with left-side zipper.  I purchased this bag for $500 a few years ago, and literally only used it once!  The one time I did use it was on an 18 degree night though, so I can attest to the temperature rating holding true.  It’s been in its storage sack the rest of the time; it’s in perfect condition.  $300 shipped obo.  I travel from Philadelphia to Fredericksburg, VA every week for work, so a local pickup could be arranged if the buyer falls somewhere in that area.
