The Big Agnes Women's Sunbeam 15° sits in the middle of the Sunbeam range, using 840 g of FireLine ECO recycled synthetic insulation for a manufacturer-rated comfort temperature of -9°C (15°F). At 1362 g it lands between the heavier 0° and lighter 30° siblings, and the mummy shape and full-length right-side zipper are standard for the line.
The synthetic fill means this bag tolerates damp conditions better than a down equivalent, useful for anyone camping in humid climates or expecting condensation inside the tent, though it comes with the usual synthetic penalty of more weight for the same warmth compared to a down bag rated to the same temperature. Draft collar and draft tube seal the hood area, and the Flex Pad Sleeve system referenced across the Sunbeam line keeps the sleeper aligned with a pad through the night.
Included stuff sack, storage sack and pad loops make it easy to transport and store. This suits backpackers and campers who prioritize reliable, low-maintenance warmth for shoulder-season and cool-summer nights over minimizing pack weight.
