Note! This product is a hammock accessory. The hammock is sold separately. An underquilt is more practical than using a sleeping pad with your hammock: it stays in its place, and you avoid having to align a slippery pad between a slippery sleeping bag and a slippery hammock. Products like this don't have standardized temperature rating tests. The manufacturer states this model offers insulation down to about 2ºC. The Moonquilt is a perfect pair to the Moonblanket made by the same manufacturer. - Measurements: 200 x 140 cm - Insulated with fillpower 650 RDS certified down - Fabric: 20 denier crinkle nylon
