NANGA AURORA 600DX Regular All Black Yamakei Down Sleeping Bag This is the NANGA down sleeping bag, Yamakei special edition model Aurora 600DX Regular. I used it for winter camping about twice after purchasing it, but it wasn't warm enough for me, so I bought a warmer model and am now selling this one. It's in a clean condition with no noticeable stains. If you're in a hurry, please let me know in advance and I'll ship it quickly. Thank you.
