Lightweight Hammock Suspension Systems

lightweight-hammock-suspension

Even from the earliest days, hangers have been looking for ways to lighten and simplify hammock suspension, particularly for camping and backpacking. Some of the first suspension systems were rope-based, which were thick, bulky, and heavy. I distinctly remember getting a Grand Trunk Nano hammock—the lightest hammock on the market at the time—and noticing that my suspension system weighed more and took up more space in my pack than the hammock. I’m not advocating going lightweight as a pursuit on its own, but rather to find a balance between safety, adjustability, low bulk, and ease-of-use.

At its core, a suspension system spans the gap between the hammock and the anchor point. It should also provide a mechanism to adjust that gap, depending on how far apart the anchors are. Some systems combine the anchoring (e.g., webbing strap) and suspension into a single system. Out in the field, you don’t always know what types of trees you’ll have to work with, particularly how far apart they might be and how big around. If your suspension system isn’t versatile enough, you could be stranded.

Over the past several years, it has been interesting to track the shifts in hammock suspension. Folks have tried everything from going shorter, thinner, and even experimenting with different knots, hardware, and related techniques. Some trends have revolutionized hammock suspension completely, such as the introduction of lightweight-but-strong Dyneema cordage like Amsteel and Dynaglide. Today, I feel we are in a pretty good place where we’re finding a balance between lightweight, low bulk (easier to pack and carry), and easy to use systems. You’ll find “camps” of hangers who advocate their favorite system such as cinch buckles and straps; Marlinspike hitch and Whoopie Slings; or carabiners and daisy-chain straps.  The “best” system is what works best for you.

In this post, my goal isn’t to persuade you to pick or switch from one system to another. Rather, I want to highlight some of the lightest systems out there as a comparison. I should also note that these lightweight systems are better suited for experienced hangers. I highly recommend new hangers start with no-nonsense daisy-chain suspension. I personally use several different systems, sometimes based on the hammock I’m using, the expected trail conditions, or sometimes just to try something new. I do think it is a good idea to know a few different techniques, particularly how to use some knots or lashings when other systems fail or don’t work.

These options are listed in no particular order. The DreamHammock and Arrowhead Equipment are very similar, but I wanted to show the effect of a different length of strap to a system. The Hammeck shows an example of eliminating the Whoopie Sling completely (Hammeck no longer sells gear :(). These three options are virtually interchangeable as each vendor (and many others like them) can each be customized to be nearly identical to the other.

Notes Remove 6-8 ft of the Muletape on each side and reduce the total weight to 100 g (3.5 oz). This system provides the most length per ounce of any system. Paul also sells Dyneema Whoopie Slings that weigh 0.6 oz (17 g), which would save 0.3 oz (8.6 g) over a 7/64 Amsteel. The Hummingbird Hammocks come with a unique “soft shackle” system to clip into the sling.

    Derek, I would like to mention a piece of hardware I have used for awhile now and is kinda generic to most any hang system. I have been using carabineers from (warbonnetoutdoors.com) they are designed not to snag on any material (no sharp edges) and are rated at around #2000, and at $10 a pair you just can’t beat the price and when used with the cinch buckle from Dutchware.com you can set up your hang in a minute (literally) and adjust it to the 1/16 of an inch if so inclined

      I’ll have to check them out. Are they just spring gate carabiners?

        Yes, but they use a round bulb on the end of the gate that matches up with a female machined socket at the closing joint (sorry, I just don’t know how to do justice to a worded explanation). I can say we (me and a few fellow workers) preformed a “”shade tree”” failure test just for fun with a fork truck and a #3800 railroad wheel (it only failed when we “bounced” the wheel while it was suspended). The design is a good one in my humble opinion.

    Was experimenting with the marlin spike rig today, come to find out the spike is actually completely unnecessary, more of a false sense of security. Since it relies on the knot itself rather than the spike it’s just as effective pulling the knot tight (pull more webbing through than ordinary to ensure it doesn’t untie while pulling it tight) & placing the whoopie over the top of the knot like ordinary. Tried it so far with whoopie & hammock bliss straps as well as the stock rope that come with the hammock bliss/grand trunk hammocks.

    Who would have thought that the toggle was just another fear backpackers pack that this UL is quite happy to toss out.

    Depending on the weight of the spikes used & the straps used it could potentially be one of the lightest setups.

    It appears impossible to get the connection to give out or otherwise cause the hammocker to fall once setup. Also makes setup/takedown impossibly easy

      If you’re just using a knot, I would recommend the Becket Hitch. More secure and more adjustability (less webbing is lost in the knot)

        I had considered that but doesn’t work overly well with the way the whoopie sling works, messes up the adjustability. Though does work with the rope very well.

    I have made myself some whoopie slings of 7/64 Amsteel and am happy with their light weight and ease of adjustability, but less happy with their limited range of length adjustability. Is there any reason you could not put a locked Brummel loop on one end of a length of Amsteel and then use a Becket hitch to tie the other end to the continuous loop on the hammock? That would seem to combine light weight, easy adjustability, and a wide length-range in one solution.

    Hey Derek! Have you used ENO’s whoopie sling, “Helios”? I’ve seen and read about it, but I’d love to hear your opinion / see it reviewed / see it added to the table above.

    Hey Derek, I’m wondering if you’ve gotten a chance to get your hands on Dutch’s new Dyneema webbing… Apparently it only weighs 2g/foot! I’d be interested in seeing your opinion on how it stacks up to other lightweight suspensions 🙂

      Yes! I’ve handled it and tested it. I would say it works just fine. I’d like to see more durability testing.
