Big Agnes Benchmark 0°

The Benchmark 0° is a synthetic mummy sleeping bag rated to 0°F, weighing 1814 g. Synthetic fill keeps performance more predictable than down if the bag or tent gets damp, at the cost of extra weight and pack volume for the same warmth. The cut is roomier than a snug mummy shape, aimed at side sleepers or anyone who shifts position through the night rather than lying still, and the water-repellent shell shrugs off condensation on the inside of a tent wall. At 1814 g it's a genuine cold-weather bag, better suited to being carried to camp than to a multi-day trek where every gram in the sleep system counts.
