This sleeping bag is in amazing condition! I ended up not using the bag but a few times. It is crazy warm and comfortable. Its a really great bag. I just live in texas and it never got cold enough to use it. This bag has always been stored laid flat and never stored in a bag or compressed. I have taken the best care of this bag period. Retail of the bag without the expander was well over $500. This is a fantastic deal on a great bag. Information about long 10° 775 fp down cheops dryloft sleeping bag by mountain hardwear.
