Kelty Cosmic 20F (Dri-Down)
Dimensions: 84″L x 24″W x 8″H
Weight: 2.5 lbs
Temperature Rating: 20F
Material: Polyester 50D
The Kelty Cosmic 20F (Dri-Down) is the best overall sleeping bag for hammocks on this list. It’s insulated with 600-fill drawdown and is thermally efficient. There’s an insulated hood and a draft tube that sits behind the 60″ two-way locking anti-snag zipper, which helps with the temperature control. It’s known for retaining heat and will keep you warm even in the most freezing of temperatures.
Our tested experience has found that this is a very affordable sleeping bag, especially when compared to top industry manufacturers like Marmot or Western Mountaineering. It’s compressible and easy to pack, you can carry it around with you wherever you go. The Dri-down technology is more waterproof than any goose or duck down, so even if there happens to be a rainstorm while you’re sleeping in your hammock, you will stay warm and dry. You can also easily store your small electronics in the pockets that are in the sleeping bag.
Unfortunately, the stuff sack seems to be low quality (a seam is splitting the threads). The only feature it loses to Western Mountaineering or Marmot is weight. It weighs 2.5 pounds, which is a bit heavy. The baffles of the bag are not evenly filled throughout the sleeping bag, so there are some cooler spots. But if you spend some time sitting out and shaking the bag, then it seems to help redistribute it a little bit and spreads the fill more evenly (we tested this in the Smokies).
Best For Big Guys

Dimensions: 35″L x 13″W x 10″H
Weight: 2 lbs

The baffles are continuous throughout, with 5 1/4in spacing. It super lightweight and weighs only 1 lb. 15 oz, which is much lighter than the Tenier Industry US Military sleeping bag.
We tested this product and found its special features to be that it’s very roomy from the inside (it fits big guys in shoulder/hip/waist girth). You’ll have plenty of space to stretch out and move around inside of this sleeping bag. You can even wear thick pajamas for extra warmth, without having to worry if there’s going to be enough space inside. It’s also ultra-packable and easy to carry around.
We tested this product in temperatures of the low 20s several times and found that there were no cold spots noticed. We even tested it in Northern Michigan! It would be top-1 if not for the price, as well as all of the WM sleeping bags we have ever reviewed. They’re fantastic! There are very reliable zippers, which are available with either left/right/opposing options for the side zippers. You won’t have to worry about accidentally breaking the zippers and having to replace the sleeping bag.

If you’re on a budget, then this sleeping bag for hammocks is the best budget pick. It’s 3.5 pounds heavier than most bags in the list, but it’s quite light for a synthetic bag.
