Feathered Friends Expedition Winter Down Sleeping Bag, the Wigeon 800+. This is a size S, suitable for people up to 170cm tall. Recently, when it comes to outdoor down sleeping bags, brands like Nanga and Montbell are popular, but this one is made by Feathered Friends, which rivals Western Mountaineering, a leading American down sleeping bag manufacturer. It's incredibly rare, and you're unlikely to see anyone else with one. Furthermore, this model was designed for the American K2 expedition team, the second-highest peak in the world. From the down filling to the draft tube around the neck for insulation, it offers high weight performance and is a genuine product that can be used in snowy mountains (rated to -23°C). Unfortunately, it doesn't come with a stuff sack. I've had negative experiences with price negotiations in the past, so they are not possible. Please understand that this is a no-claims, no-returns sale. I will be going to a ski resort for work in late November, so this is a limited-time listing. It will be removed on November 20th. Thank you.
