NEMO Disco 15 review

The Disco 15 is the bag we would point most campers to first because it pairs a real 15°F class rating with a cut that suits how people actually sleep. NEMO lists an ISO comfort rating of 27°F and an ISO limit of 16°F, filled with 1 lb 8 oz of 650 fill power RDS-certified down. The spoon shape measures 70 inches at the shoulders and 68 inches at the knees, so side sleepers can draw their legs up without fighting the bag. Two Thermo Gill vents on the chest open from inside or outside to dump heat, and the Blanket Fold draft collar seals the neck on cold nights. The hood and footbox use a waterproof fabric to resist tent condensation. The tradeoff is weight: the Regular Wide has a 2 lb 13 oz minimum weight and an 8.8 L compressed volume, heavier and bulkier than the 900 fill Therm-a-Rest Parsec. At $329.95 it costs far less than the premium ultralight bags here.
