Kelty Cosmic Synthetic 20 Women's

The Kelty Women's Cosmic Synthetic 20 is a mummy-shaped bag insulated with CirroLoft ECO synthetic fill, tested to -4°C comfort and -11°C limit — a solid three-season choice for spring through fall. The 1300 g fill sits inside a 380T nylon taffeta shell with DWR treatment and a 50D/300T polyester taffeta liner, both made from recycled, PFC-free materials. Synthetic insulation means extra weight compared with down bags in the same temperature class — 1810 g total and a warmth-to-weight ratio of just 6.1 — but it retains its insulating properties when damp and is easier to care for, which suits wetter terrain, stream crossings, or hikers who value low-maintenance gear over shaving grams. A contoured, fitted hood, draft collar, and draft tube along the zipper cut down on heat loss, and an interior pocket holds small items overnight. The women's-specific cut fits users up to 172 cm, and a stuff sack is included.
