The popular Siren™ has been updated in 2019 with a vertical baffle structure, lighter weight and smaller pack size. This 45°F backless quilt is ideal for ultralight treks where weight and versatility matter; it takes away everything extra without taking away the promise of a warm and draft-free night's sleep. Constructed using the highest end fabrics and premium 850 fill power down, Siren™ is one of the lightest quilt-style bags on the market.
The backless design shaves weight, and the stretch footbox anchors around pad and keeps it securely in place. A cord system lashes around the underside of the pad to accommodate a variety of pad sizes.Features
