NEMO Forte 20 review

The Forte 20 gives side sleepers NEMO's spoon shape with synthetic insulation instead of down. NEMO lists an ISO comfort rating of 29°F and an ISO limit of 18°F, which is close to the Disco 15 and the Parsec 20. The insulation is Zerofiber 800 PCR, a synthetic fill that keeps insulating when damp, which suits wet coastal trips, canoe camping and anyone who prefers to avoid down. The cut matches the Disco, with 70 inches at the shoulder and 68 at the knee. The cost of synthetic fill is weight and bulk: the 20°F Regular Wide has a minimum weight of 3 lb 10 oz and compresses to 11.9 L, the heaviest and bulkiest bag here. That makes it a better fit for car camping and short backpacking trips than long hikes. At $229.95 for the Regular Wide it is $100 less than the Disco 15, and a 35°F version starts at $169.95.
