The Kelty Mistral Kids 20 is a children's mummy bag with Recycled Cloudloft Eco insulation made from recycled fibers, rated by the manufacturer to -1°C comfort / -7°C limit — a more technically equipped, mummy-shaped alternative to the simpler Callisto 30 rectangular kids' bag, built for three-season use.
At 1080 g total with 621 g of fill, its warmth-to-weight ratio of 6.5 is a strong figure for a children's bag, comparable to the adult models in the Mistral line. The recycled 68D polyester taffeta shell carries a DWR finish, and the adjustable contoured hood is backed by a draft tube along the full-length two-way zipper. Internal length is 175 cm with a 152 cm maximum user height, appropriately sized for kids; it packs to 43 x 23 cm and includes a stuff sack.
Thanks to its lower weight and decent temperature range, the Mistral Kids 20 works for lighter family trekking with a child along, not just tent camping — a clear step up from the purely camp-oriented Callisto 30.
