Hey Hikers... I have an older, circa 1990's (+ or -) REI sleeping bag that I know nothing about. It is a heavy (4 lbs, + or -) down bag with hood. The colors are purple on top and black on the bottom. The inside is black. There is a red, heavy-duty zipper guard 'ribbon' running the length of the zipper and also attached to the purple, substantial draft tube. The zipper length is 3/4-ish. A unique feature of this bag is that there is also a substantial, U-shaped neck draft tube that is attached to the top of the bag, so that it hangs down. It resembles 2 triangular shaped pockets that hang down around the neck area. There is a smallish REI label on the foot box and a washing instructions label just on the inside of the bag. Nothing else. This bag has a TON of loft.
I spoke with REI. No idea... Any thoughts? Thanks much!
