photo: Kelty Cosmic DriDown 20 3-season down sleeping bag

The Kelty Cosmic 20 is one of the most affordable sleeping bags you can find that's filled with down insulation. Although it's not exceptional in any particular aspect, it provides decent comfort and warmth in a package that is small and light enough for some 3-season backpacking. Unfortunately, its 550-fill power down doesn't offer impressive loft or substantial benefits compared to synthetic insulation.

  • Only 3-season, not great for colder weather

Sliding into a fluffy sleeping bag after a long day of hiking is one of the most satisfying experiences on the trail. The daytime is meant for traversing ravines and climbing mountains, but at night all a weary explorer wants is to shimmy into a warm cocoon and catch some Zs, swaddled snugly in a cozy cloud like a little angel baby.

Thing is, sleeping in a cloud would be awful if you think about it. You’d be wet and cold, not to mention hundreds of feet in the air. Feathers are more comfortable, especially DriDown-treated feathers. Trust me. So, rather than clouds, we suggest the Kelty Cosmic Down 20 sleeping bag. For the price, you’d be hard-pressed to find a better bag.

The 600-fill of hydrophobic down is wrapped in a durable 50D polyester taffeta liner and a ripstop shell, all of which is shaped into a mummy-style bag that hugs your body in the right places. Features such as the adjustable hood, draft collar, and draft tube work well to hold in your warmth. Clouds? They just don’t come close.


Owned it for a year. Finished 3 trips with it.
I have used other bags but not from Kelty.
I only used the product during spring and summer months
