Big Agnes Women's Sunbeam 30°

The Big Agnes Women's Sunbeam 30° is the lightest and warmest-rated bag in its family, using 756 g of FireLine ECO recycled synthetic insulation to reach a manufacturer-rated comfort temperature of -1°C (30°F). At 1244 g in the Petite size, it is the pick within the Sunbeam line for summer trips and warm shoulder-season nights where the 0° and 15° versions would be overkill. The mummy shape with 152 cm internal length is cut for the Petite size range, up to 167 cm, and packs down to roughly 19 x 18 cm — compact enough for a backpacking pack, if still heavier than a comparable down bag at the same rating. Stuff sack and storage sack are included for transport and long-term storage, and the recycled-content synthetic fill keeps performing if it gets damp, unlike down at this price point. This is a straightforward warm-weather synthetic bag: not the lightest option available for 30°F comfort, but a low-maintenance one that doesn't require the careful drying and storage down demands.
