Who says you can’t find comfort fast? With dual-temperature technology, the Tumbler 30/50 sleeping bag easily adapts from fall to spring as the weather shifts. Use the side with a thick layer of Cloudloft™ insulation to stay toasty when there’s a chill, or flip the bag to the more thinly insulated side when the nights start to heat up. To up the cozy factor, there’s also a soft cotton-blend liner and locking side zippers for easy ventilation. Lie down, flip when hot, sleep.

Features:

Kelty Cloudloft™ insulation offers soft, high-loft warmth with durable compressibility
On colder nights, or a chilly pre-dawn use the thicker insulated 30F side of the bag
On warmer nights, flip the bag over for a little less insulation on the 50F side
Locking zippers  with dual sliders - allow for easy venting or fully unzip and use as a blanket
The full length draft tube with antisnag zipper construction ensures warmth and easy-maneuvering through the night
The Tumbler series includes external snaps, to secure it inside another rectangular bag, as an added warmth layering system
Or, use the liner loops to secure an extra layer inside the Tumbler on chillier nights
