Cosmic 20

Kelty's Cosmic Down 20 is a 550-fill-power down mummy bag in a semi-rectangular cut, 1106 g in the Regular length. Fill power measures the loft of a given mass of down: 550 is a modest figure, so the bag reaches its rating with more down mass and therefore more weight than an 800-fill bag would. Kelty publishes a 20 F rating as its own number and does not publish ISO 23537 comfort or limit figures, so it cannot be compared directly with bags that do.
