Kelty KID'S CALLISTO 30

The Kelty Kid's Callisto 30 is a rectangular children's sleeping bag with Cloudloft synthetic insulation and a manufacturer limit rating of -1°C, sized for users up to 152 cm tall. It's a simple build with no water resistance treatment listed, so it's meant for tent or indoor use rather than exposure to rain. At 1160 g with 800 g of fill, it's fairly heavy for a kids' bag, though that tracks with the roomy rectangular cut and the absence of weight-saving features like a hood or draft collar. The shell combines 190T polyester taffeta with 260T polyester pongee, and the liner is 190T taffeta. A stuff sack is included, packing to 38 x 23 cm. For family camping, sleepovers, or a child's first camping trips, the Callisto 30 is a practical, low-fuss choice — but its weight makes it a poor fit for genuine lightweight trekking with a child in tow.
