Big Agnes Benchmark 35°

The Benchmark 35° is a synthetic mummy sleeping bag rated to 35°F, weighing 1134 g. Synthetic fill is more tolerant of damp conditions than down, though it packs down less and weighs more per degree of warmth. The roomier mummy cut suits side sleepers and anyone who shifts position overnight rather than a snug, minimal-fabric shape, and the water-repellent shell handles condensation and light dampness. At 35°F and 1134 g, this is a warm-season bag for mild nights, not one to carry into near-freezing conditions where a warmer-rated bag would be the better call.
