REI Co-op Magma 30 Sleeping Bag - Women's

The women's REI Co-op Magma 30 shares its 850-fill-power hydrophobic goose down with the men's version but differs in cut, baffle construction, and stated temperature ratings. A -2°C comfort rating and -8°C limit sit colder than the men's numbers, which is typical practice — women's bags are generally rated to a lower comfort temperature at comparable fill under the EN 13537 methodology, reflecting targeted extra insulation around the torso and feet. The 320 g of fill is arranged in box-baffle construction with horizontal chamber orientation, which resists down migration better than simpler stitch-through designs used on some lighter bags. The full-length zipper is two-way, unlike the men's version. Shell and liner match the men's bag at 15D Pertex Quantum and 15D ripstop nylon respectively. The foot box is trapezoidal for extra room around the feet, and there's an internal pocket for small items. In regular size (fitting up to 167 cm), the bag weighs 638 g, and both a stuff sack and storage sack are included. The materials are PFC-free.
