I purchased this from an online select shop. I tried it on after purchasing, but it didn't match my image of it. I haven't worn it outside, so it's almost new. Please note that the stuff sack is missing. The following is a quote from the website: These pants provide high insulation, capable of withstanding extremely cold environments, with a generous amount of high-quality 800 fill power down, packed using a unique construction developed for sleeping bags. The outer fabric is treated with a water-repellent finish boasting world-class water repellency, making it difficult for snow to adhere. While voluminous, the three-dimensional cut makes it easy to move in, and the seat and knee areas are reinforced.
