Premium value

The one thing that you have to take away from the Kelty Cosmic Down 20 is a simple fact that you will not find a better sleeping bag even close to this sticker price. Where most bags purpose built for the outdoors and serious backpackers are well above the $300-$500 range, you’ll be able to save a significant amount of money while sacrificing a minimum amount of performance, and will be able to use that savings on more essential gear.

Pretty comfortable

While you would be beyond hard-pressed to find anyone that thought that this bag was a real looker, the Kelty Cosmic Down 20 more than makes up for things the comfort department. A 550 fill real deal down bag, you’ll be able to enjoy real heat and comfort you expect on even the coldest nights. With a temperature rating of 20°F, you can reasonably expect this to be able more than adequate three season bag, though it might get more than a bit hot in the summer. The other main feature of the comfort comes in the simple fact that you will have to lug and tell a massive sleeping bag around. While not specifically and purpose built to be an ultra-light sleeping bag, weighing in at a little over 2 pounds the Kelty Cosmic Down 20 is nothing too terribly difficult to manage. It compresses easily enough to stowaway without taking up precious space in your go bag, while still giving you reliable comfort that you deserve.
