Big Agnes Torchlight 20°

The Torchlight 20° is a mummy-shaped down sleeping bag built around Big Agnes's signature expandable side panels, which unzip to add up to 10 inches of girth at the shoulders and hips — a way to trade a small weight and pack-size penalty for the fit flexibility of a wider bag on demand. Insulation is 600-fill-power down treated with DownTek's hydrophobic finish, which helps the fill keep lofting and insulating even if it picks up moisture from condensation or a damp tent floor, at the cost of the extra warmth-per-gram you'd get from higher-fill-power down. At 1216 g total and a comfort/limit rating of -1°C/-7°C (EN ISO 23537 tested, so directly comparable across brands), this sits toward the heavier end for a 3-season bag, reflecting its 600-fill insulation and box-baffle construction rather than an ultralight build. A boxed, adjustable hood, dual draft tubes, an internal pocket, and included stuff and storage sacks round out a bag better suited to car-adjacent backpacking and cooler shoulder-season trips than to gram-counted thru-hiking.
