Despite the forecasters' best efforts, weather can be unpredictable – but the Tumbler 30/50 Dual Temperature Sleeping Bag from Kelty will keep you comfortable whether it's cool or downright cold. One side is thick, the other is thin, so you can sleep under the one that best suits the weather conditions.
The CloudLoft synthetic insulation is more heavily concentrated on one side of the bag than the other, producing a comfort rating of 30°F/50°F. The liner is a sleep-friendly poly-cotton blend, while the shell is a lightweight but durable 50 denier polyester rip-stop. Internal loops allow the use of a removable liner, and external snaps can be used with to secure the Tumbler inside another rectangular bag for even more warmth.
The 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.
