Some of the best sleeping bags for hammocks are spacious and comfortable, so that you can stretch your legs and not feel crammed.

Sleeping in a hammock is comfortable and allows you to pretty much sleep anywhere you want to.

We are not going to estimate the sleeping bags by right or left zipper, as this feature may change in the opposite way depending on if you’re a left or right-handed person.

We also researched that the best choice for hammocking is a hooded mummy sleeping bag, so it’s actually the “best hooded mummy sleeping bags.” We also do not consider style, design, or color since it’s a matter of personal taste.

Best OverallKelty 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).

  • Compressible
  • Waterproof
  • Extremely thermally efficient
  • Heavy
  • Uneven baffles

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.

The zipper snags easily so be mindful when you’re opening and closing the sleeping bag.

  • Heavier than competitors
  • Lacks shoulder space
  • Lacks pockets
