Western Mountaineering Slinglite I'm selling this because I bought it several years ago and haven't used it much. The following is the manufacturer's description: MADE IN USA, hammock underquilt filled with 850+ fill power goose down. The Slinglite is an underquilt for hammocks. It wraps around the outside of the hammock, shutting out the cold from below and providing insulation. It contains a generous 225g of down. The loft of the high-quality 850+ fill power goose down expands to the maximum, completely shutting out the cold, and providing peace of mind even below freezing. It's very easy to use, with clip hooks to hang the ends, drawcords on both ends, hooks to hang on the sides of the hammock, and adjusters to adjust the overall length. - Clip hooks to hang the ends - Drawcords on both ends - Hooks to hang on the sides of the hammock - Adjusters to adjust the overall length - Fits most gathered-end hammocks - Includes stuff sack and storage sack Spec Fill: Goose down (850+ fill power) Fabric: 15D silnylon taffeta Size: 6'3" = 188cm Inner Circumference: Center = 115cm, Ends = 97cm Average Weight: 370g Down Weight: 225g Temperature Rating: -7 degrees Celsius
