Kelty Callisto 20 Sleeping Bag

Enjoy freedom of movement while staying warm in temperatures down to 20°F with the Kelty Callisto 20 Sleeping Bag. Filled with synthetic CloudLoft insulation, the bag is designed to minimize heat loss while giving you room to shift around during the night.

The Callisto’s snagless zipper is lined with a full-length draft tube to prevent heat from leaking out. The zipper locks at the top, so it won’t slip down and chill you in your sleep, but also has sliders at the top and bottom to allow ventilation where you need it in warmer weather.

Offset construction prevents heat loss through stitching lines for consistent comfort with no cold spots. Attachment loops keep the bag from sliding off your sleeping pad. To make a bag sized for two, simply zip two Callistos together to form a double-wide.
