This is a like new Feathered Friends Vireo made with 900-fill down and the latest Pertex Endurance UL shell fabric. It's ridiculously warm for its meager 16oz. and packs ultra small. The bag is orange, has been used only a handful of times (it was a test model), and is in near perfect condition.
The normal 900-fill Vireo retails for $299, but this one has the better shell fabric, which adds another ~$50. You can have the bag for $175, including shipping.

Description from Feathered Friends:
The Vireo was designed with alpine climbers in mind. It has no zipper, no hood, a variable down fill and weighs only 16 ounces. A variable down fill means that the lower part of the bag has more down fill (rated to 25) and the upper section has less fill (a 45 rating). It is designed to be used with the Volant Jacket (or Hooded Helios or Frontpoint parka) for full protection. Used without the jacket it becomes a summer bag. This compact, light system is great for climbers, bicyclists or emergency use.
