The Kelty Women's Mistral 20 is a mummy-shaped bag insulated with recycled CloudLoft ECO synthetic fill, carrying a manufacturer limit rating of -7°C for three-season use. Shingled baffle construction keeps the 890 g fill in place and resistant to shifting, and both shell and liner are 68D recycled polyester taffeta with DWR treatment.
A warmth-to-weight ratio of 5.2 at 1340 g total weight puts the Mistral 20 among the heavier synthetic bags in this temperature range — the trade-off synthetic insulation typically makes for better wet-weather performance and a lower price than a comparably warm down bag, which makes it a sensible pick for damp climates or less weight-obsessed hikers. The two-way zipper allows venting on warmer nights, while the draft collar and full-length draft tube limit heat loss along the zip. The bag has a women's-specific anatomical cut, fits users up to 173 cm, and ships with a stuff sack.
