Bears Rock -30 Degree Sleeping Bag, Winter Use, Wide Type, Envelope Style, FX-503W - Color: Brown - Storage Method: Roll up for storage - Use: Outdoor sleeping bag Thank you for looking. Type: Envelope style Features: For winter use Purchased for camping and used only once. It was quite large even when stored, so I am selling it to buy a replacement. It is in almost unused condition, but please understand that it has been stored by an amateur and is non-returnable. Compared to mummy bags, the face area can be cold, but I believe this is one of the warmer types of envelope sleeping bags. *The instruction manual will also be included, but I handled it carelessly and it is partially torn. (The tears are minor enough that the content is still readable.) Thank you.
