This sleeping bag was my wife's. She used it on a single trek in Nepal. Not planning on doing activities for this temperature rating anytime soon, so, here's your chance to get a high end sleeping bag. It's the Reg. size. We've stored laid flat under a bed, it's loft is literally like new. It comes with it's original compression stuff sack, original storage mesh bag, and synergy connecting straps. Super clean, immaculate condition. She just doesn't need it. It retails new for $800, yours for $550. 12 days of use. 

Full specs in this link here, but if you're looking, you probably know what this bag is all about and you're familiar with the Polar Ranger.
