I have a Marmot Plasma 15 w/ 900 fill down standard length in perfect shape. Lightly used. It is about 30oz (or 1lb 14oz converted) for a 15° bag. It is very warm, light and comfortable. Materials and construction are high quality. This bag is originally for around $600!

It has been stored in a dry place in it's large "long-term" storage stuff sack as to keep the down lofty. Since getting a quilt, this bag hasn't seen much use.

Here is the Outdoor Gear Lab review on it.

Selling for $250. CONUS. Paypal, etc.

I can get you pictures on request. PM me!
