Whether you're new to the outdoors or you're just due for a new bag that doesn't break the bank, the Kelty Cosmic Down 20 is the best option for the money to get you going, making it our Top Pick for budget backpacking and camping. There are other bags in our review which are lighter, warmer, and more compressible, but the Cosmic Down offers decent quality for an incredibly good price. It is available in other temperature ratings too, just in case 20° F doesn't fit your needs. See how this sleeping bag compares to others in our Backpacking Sleeping Bag Review.
If you like the great performance-to-price ratio of the Cosmic Down 20, but want to push your adventures into colder climates, Kelty has you covered with the Cosmic Down 0. As the name implies, this bag's temp rating is 0F. All that added 600-fill power DriDown does make it pretty heavy at 4.13 lbs., but its $220 price tag is a great price for a 0F bag. The products in the Cosmic Down line from Kelty share the same design, fit, and materials, so if you like everything about the 20 but want more warmth, we think you'll dig the Cosmic Down 0.
