We offer both single and double layer hammocks to suit your specific needs.
Here are a few of the things you should consider in choosing a single or double layer.
Body Weight - Depending on the fabrics used, a double layer will normally provide a more solid feeling and supportive hammock and minimize stretch. This is less of a consideration with many of the newer, stronger fabrics available. For a rough guide on comfort ratings, please check out our Comfort Rating Calculator or our Hammock Calculator.
Bottom Insulation - Sleeping pads can be terribly frustrating in a single layer because they're always trying to squirt out from under you. If you intend to use a sleeping pad, a double layer hammock works much better. If using an underquilt, a single layer hammock is usually sufficient.
Durability - A double layer hammock can provide you a little more safety margin against abrasion damage or snags. In some cases, a tear or snag in a single layer hammock can mean the end of a trip and/or a cold night on the ground. A minor snag or tear in a double layer hammock can often be repaired as long as the damage is contained to only one of the two layers.
Pack weight - Obviously, a single layer hammock is lighter than a double layer. See our Hammock Calculator for a rough idea of the difference.
Wind blocking - A double layer of fabric will block more wind and can potentially provide more warmth than a single layer hammock. This of course, is a good or bad thing depending on the season.
Insect Protection - Some people claim that a double layer hammock will provide more protection from insects getting to you from below your hammock. I'm not at all sure of this because I personally always use an underquilt or sleeping pad under me. Also, I treat my personal hammocks with permethrin to combat insects and I've never once had this issue.
Price - If you don't need a double layer, you can save some bucks with a single layer.
Heavier layer on the outside or inside?
Definitely on the outside. This provides you the best durability against damage from brush, saplings, briers, etc. Also, this makes for a stronger hammock that will last longer if you are using a sleeping pad. Using a double layer hammock together with a sleeping pad of any substantial thickness places almost all the stress on the outside layer only until it stretches out and is "helped" by the inside layer. If the users weight greatly exceeds the capacity of the outside layer, damage or failure can easily occur.
Are the double layer hammocks sewn together?
Yes. The 2 layers are sewn together along the sides, leaving approx 24-26" open on both ends. This gives you the ability to easily insert and adjust a sleeping pad or supplement your insulation between the layers.
Why leave the ends open instead of the middle?
• The middle edge is a high stress area when entering or exiting the hammock.
• The 2 layers don't tend to shift around nearly as much.
• Easier access to the ends (and air valve) of your sleeping pad.
