I bought this to use as a blanket for car camping, but ended up not using it, so I'm putting it up for sale. I've never taken it out of the storage bag, and I haven't used it as a sleeping bag or blanket, but since it was left in the car's luggage compartment, I'm listing it as "Like New." ───────────────────── The following is an excerpt from the product description: A casual envelope-type sleeping bag, the "Rectangular Padding Bag," made with quick-drying synthetic fiber cotton. It can also be used as a cushion when stored in the included storage bag. It can also be connected to two bags. An envelope-type sleeping bag, which is rare in the NANGA lineup. It's useful for camping in warm weather, and it's versatile, as you can open the L-shaped zipper to use it as a blanket, or use it inside another sleeping bag in cold weather. The filling is made of polyester, and the amount of filling is 800g. It can also be used as a cushion when stored in the storage bag, so it can be used all season.
