The spacious and durable Eagles Nest Outfitters DoubleNest is an excellent hammock for outdoor lovers. It's wide and tough enough to fit two people comfortably. It also comes in a bunch of different color combinations. It's heavier than the hammocks we prefer to backpack with, but it’s perfect for camping, hiking, and trips to the park. For the same dimensions but nearly half the weight, we recommend checking out the ENO SuperSub Hammock.
A lot of folks think all you need is a sleeping bag to stay warm in a hammock. After all, you’re off the ground, so you don’t need a pad for comfort. What that pad does help with, however, is warmth. You’ll compress the sleeping bag insulation under your body in a hammock just like you would on the ground, so you’ll feel cold in a hammock without some uncompressed insulation beneath you. To keep the sleeping pad from slipping out from under you, try putting it inside your sleeping bag.
A water break—or drip line—is a piece of line added to all lines running under the hammock tarp to provide a path for water to the ground. They are not included on some hammocks, and instructions lack detail on the need for them. Sometimes suspension hardware, like a Dutch Biner, provides some water break, but always add a drip line for the cheap insurance it provides. Videos that further investigate the how and why of drip lines are linked below. This <$1 item protects sleeping gear from getting wet. A cotton shoelace works great, but other options are below. I wrapped a small piece of line around the suspension line and tied a taut line hitch. This seemed to stay tight on the line better than other methods.
Hammocks have been used as traditional bedding for thousands of years. But just now, they’re starting to gain ground in modern sleep science. The indigenous people of Latin America have long embraced the use of hammocks. Even to this day, some people grow up sleeping in a hammock every night. The Navy also replaced their cots with hammocks shortly after Europeans discovered them in South America. Sailors spent months at a time aboard sea vessels where each man was assigned a hammock.
When you have a hammock, your campsites are limited by imagination. All you need is a couple of trees the right distance apart. What is under you may not matter at all. I have personally slept on the side of a mountain, and on the Hennessy web site, there is even a photo of a guy sleeping over his boat in a swamp. There are things that make better camps than others, and some safety things to consider, but unless you are camping where there are no trees, then the hammock will increase your camp sites.
I think what gets tricky here is the difference between a catenary angle and a straight line angle. When you measure the angle you want the hammock in a straight line. I usually put a small item in my hammock to tighten up the line without weighing it down too much. It’s a little more art than science. The calculator and thumb-finger methods are starting points but don’t take into account fabric type and stretch with all the components, all of which affect the final angle, which is what we are estimating. If you find the hang angle is too slack, tighten it up. Fiddle a little until you find the right hang angle for your hammock.
Your sleeping bag must resist low temperatures and assure you protection from the cold at night. Also, it should be 100% waterproof, not only to avoid getting wet because of the rain (which should not be a problem if you have your hammock tarp), but also to protect you from the moisture in the air, which can be very high at night or in bad weather conditions.
Several of the expedition models had a bit of a learning curve to their set up to be able to get comfortable. The Warbonnet Blackbird and Ridgerunner fell into this category, but after practice, we were able to set them up with relative ease and confidence. Additionally, some slings don't come with all the components you need to set them up — beyond just a lack of suspension system. Both the Warbonnet Blackbird and both Hennessey models lack the stakes necessary for a complete set-up.
In a tent you lose the air flow (even with the windows open), you lose the stars, you can’t stand up to do anything and you can’t easily see what’s around you. You often fall asleep in a cold box and wake up in a hot and stuffy box and, if you’re lucky, you didn’t roll over into that puddle that’s somehow accumulated in the corner even though your tent’s supposed to be waterproof.
