Summary

Excellent! Comfortable, rain-proof, bug-proof, easy to set up and take down.

Pros

  • Comfort
  • Very effective bug net
  • Easy to set up/take down
  • Stands up to rain and wind

Cons

  • Black fly lines hard to see in the dark
  • Doesn't include stakes

Me: 210 lbs. Female, 30 y/o. You don't have to be old to want to sleep soundly in the wilderness.

I used the entire setup as intended. I did pay attention to wind direction when choosing trees and setup. The asymetrical design made it very easy to point it in a wind-resistant position every time. Depending on wind, the lines to stabilize the fly work best staked and stakes aren't included (though I always find a free stake or two every time I go camping). In addition, those lines are black and hard to see at night, I may replace them with yellow or reflective lines. 

Setup: So easy to set up and take down. The first time the knots took a while using the instructions printed on the bag, but after doing it twice, it became second nature. I have noticed easier/faster knots on YouTube and haven't tried any out yet to see if they hold as well.

Stability: Didn't sag at all. Once set, it stays. 

Rain/Wind ResistancePoured rain 3 nights in a row and stayed bone dry. One night had gusts of 25 mph, I was awoken by the large sway in the hammock, but stayed stable and dry all night long, though I was terrified of trees falling on me.

The fly sheds water VERY well. This helped it dry really fast when we got our 1 hour of relief from rain, which my companion's tent fly did not. 

Cold Weather Resistance: Slept in temperatures of 35 to 60 degrees F. I used a regular lightweight inflatable sleeping pad and normal sleeping bad rated to about 40 degrees and was warm enough. 

Ventilation: Plenty of fresh air. The one night it got down to 35 degrees F I woke up with a sore throat due to breathing in cold air all night, but felt great while I was in it. 

Room & Storage: Roomy for sleeping. Achieved comfort on my sides and back. I only tried it in bear country so I never attempted to store any gear inside hammock with me. Kept my journal and flashlight in the pocket provided.Was suprised at how much room there was to spread out. You can lay longways, diagonally, or I tend to lay in the middle with my knees out to one or more sides - plenty of room and support for all of that.

Packability: Snakeskins are included when you buy direct from Hennessy. I bought my separately, and totally worth it. Made setup and take down less than 5 minutes and made packing easy. About 3 lbs, but packed away nicely. Personally find it better than traditional solo tents.

Ease of Use: So easy! Can't say this enough. 

Construction & Durability: Well constructed. Took a beating on the rough trip, but still in its first few months of use. I'll update if time proves it to be less.

Bugs: Totally effective at keeping out mosquitos, no-see-ums, etc. The first night about 4 got in with me and I got all of four of them pretty quickly. Keeping my flashlight on though resulted in a solid layer of mosquitos on the inside of the fly (but outside of the bug net). The angle of the fly made for a VERY loud hum inside in the hammock which was quite annoying even though none could actually touch me. 

Features:

Tree Saver Straps: Included with hammock, fit all the trees I found wonderfully. Used them on trees with diameters from 5 inches to 25 inches.

Modifications: Aside from switching out the lines, the very last night was beautifully warm and clear, so I tied a straight line about half an inch above my hammock lines on the trees. This provided more room between the fly and hammock so I'd get more air and could see the sky by looking out the end.

Nice review, Siltloam. I've been a novice hanger for a while now, but if I ever decide to go all-in, this is hammock is high on my list.

I actually got this BECAUSE I was a novice. The all-in-one guaranteed comfort in many conditions all at once. Since the ENOs sell each piece separately, I know my cheapness would prevent me from getting the bug net and the rain fly for a while. So instead I started with everything for max comfort, and am learning modifications as I get more comfortable with hammock sleeping.

Great review, Siltloam, and as a fellow HH Expedition user, I agree with all your points. My Expedition is my most comfortable shelter, and even though it is heavy compared to lighter tent options, it is a quick, easy, and complete system that I feel makes finding a spot for the night easier than when I have to use a tent in tree country.

Thanks for the hammock review, an Expedition UL was my 2nd hammock. I enjoyed it and learned a lot from it. You;re right about the guy lines, I swapped mine for MSR camlocks. I read that you had a sore throat from cold air, check out the HH over cover, I found it worked excellent for creating a warmed micro environment within the hammock.

Rating: rated 4 of 5 stars

Price Paid: $169.95

Summary

An excellent all-in-one hammock system that won't break the bank. A little on the heavy side, and improved with some slight modifications. Overall a great introduction into the world of hanging. Protects from the elements, and is ideal for camping, hiking in most of the Northern hemisphere.

I recommend the Hennessy hammock system to anyone looking for a full on 3-4 season hammock/shelter system and that spends a good amount of time in areas with trees.

Pros

  • Versatile multi-season sleep system
  • Durable
  • Comfortable
  • Reasonably priced
  • Hennessy offers all components
  • Easily modified
  • Easy to set up
  • It's a hammock :)

Cons

  • No trees.. No hang
  • Heavy for a hammock
  • Provided suspension not the best
  • Shoddy weight rating

Ahhh Hammocks! Providing me with the best nights' sleep in the woods, a place to relax during the day and a swinging chair when I just want to sit and.. well...  swing.

Tom Hennessy and Hennessy hammocks provide a relatively easy and fairly inexpensive opportunity to break into hammock camping. The part I liked the most was that you can place one order and have everything you need to run out into the woods and "hang" out for the night. Mind you I have been sleeping in an ENO for some time and researched many, many options. It was the all-in-one package, along with a nice sale on the 4-season insulation system that sealed the deal for me.


IMG_20140621_195759_553.jpg

Here you have the Hennessy Expedition Asym (for asymmetrical) Zip model, I upgraded to the larger Hex fly, got the 4-season insulation and modded the support ropes with Stews "whoopie slings" and tree straps on a marlin spike toggle. Here is a pic; hanging off a section of the North country scenic trail in WNY.

  • What you get: A basic order will get you your hammock; you can choose from a bottom entry or a side zip model, heavy duty climbing grade rope attached at each end (~10'), 42" tree straps ( essentially webbing straps to protect the tree bark), stuff sacks and a basic fly cover. All for around $200 shipped (depending on the model). Additional options include; larger tarp options, 4-season insulation system, snake-skins (tubing to slide over your hammock), and water catch funnels.
  • Setup: Setting up a hammock is by far one of the easiest chores of camping for me. Find two trees roughly 12-25' apart encircle each tree with a webbing strap, and tie in your provided rope at the desired height and you're done. Granted there is some fiddling to get it just right, learning the proper methods, knots takes a bit, but like anything else once you got it down it's super easy. Hennessy gives great tutorials on set up and the stuff sacks come or at least used to come with directions printed on them. 
  • Warmth/Ventilation: I have only had this hammock in temps ranging from 30f - 78f With the 4-season insulation system and my Therm-a-rest alpine down blanket I was always comfortable. Granted I hang my hammock slightly different than the fly to ridge-line method that is stock (also a nice easy and fully functional system, just not how I hang). But I never woke up wet or cold.

    Now anything below 40f for me requires an under insulation, everybody is different with cold tolerance. Rest assured even the slightest breeze can literally suck the warmth from beneath you in a hammock. Sleeping bags DO NOT properly insulate. Once the loft of your bag is compressed it becomes useless. I promise, I learned the hard way. Here's me in ANF, PA. The nights hit around 9-15 degrees f. In my ENO and a military -40 sleep system, full thermals, fleece, down coat and I could still feel the cold at my back on the bottom.
    IMG_20131123_080900_559.jpg
  • Comfort: I had tent camped for years, eventually my back and my side sleeping habits put a halt to any real quality sleep in the woods. My first hammock (ENO SingleNest) was very nice and got me hooked. But the asymmetrical cut of most modern hammocks allows for a nice flat lay. You can still lie straight if you like, but I like the support of the asym hammocks.
  • Interior space: I am 5'8" 160#, I have more than enough room. There's a handy gear bag hanging from the ridge line that you can fit your phone, flashlight etc. into. I can slide side to side and up and down with no issues. I generally have my down top quilt, my clothes sack for a pillow, and what ever i had in my pockets go into the gear bag. The integrated ridge line (rope that runs the length of hammock from tip to tip) keeps the bug netting off your face and the integrated shock cords on either side allow you to "spread out" the width as well. If you've slept in a mummy bag you'll have no issues here.
  • Packing: Here's where the Hennessy lost points in my book. The hammock alone weighs in at 2.5#, once you have all your gear in there you're around 5# for a 3-4 season hammock. Which isn't terrible but definitely heavier than other (more expensive) hammock brands. Stuffing all this into the provided stuff sack is ridiculous to try to put into your backpack unless you have a huge pack. The hammock and fly take a lot of real estate.

    My trick: I keep my hammock in the snake skins and snake the entire tube along the back of my pack, then make a bow-line or figure 8 with the suspension rope and clip it to the h2o clip for easy access. I then proceed to pack my bag like normal.
    IMG_20140712_214400_221.jpg
  • Side notes: I found the provided suspending ropes stretched a lot throughout the night and I would wake in the morning with my butt just skimming the ground. I swapped them out for Whoopie Slings; a stronger and lighter option. The standard fly is just plain silly in my book; it's just enough to cover the hammock, not even sure how it would perform in driving rain. I upgraded to the Hex fly, essentially creating a tarp shelter around my hammock, very versatile can be pitched lower or at various angles to provide better views etc.
    20140405_193215.jpg

This is the toggle setup. I went with the longest webbing straps offered, and the Easton aluminum cut toggles to get around the big tree issue. Looped around that are the whoopie slings which I swapped out the original suspension ropes for. It's also a faster set up.
IMG_20140620_175901_243.jpg

Final Thoughts: I really like this hammock, I take it everywhere I go when I'm solo sleeping. For me it is truly a comfortable 4-season sleeping system.

Note: I have decent cold tolerance. Not everyone can take this setup into below 40 or even 50 degrees. Additional gear may be required. Also, If you are taller than 6' look into the larger hammock options. They do offer ultralight models at a higher price tag as well.

I will say if I could have afforded it there were definitely other options I would have gone with. But, don't let that take away from the decent product Hennessy has. Please let me know if I missed anything.

Nice review, Justin. Most folks need under insulation in temps below 70F. I've spent many sub-freezing nights in hammocks. A good UnderQuilt or a pad (with extenders) will provide that under insulation. If you ever own a double-layered hammock, you can even use a sunshade made for car windshields (though they'll fold up on you in a single layer hammock).

Good point GOOSE. I forgot to mention that Hennessy does offer a precut bubble wrap/mylar windshield sheet for the hammocks, but it's way cheaper to buy one from an auto parts store and cut it to fit. And don't be alarmed if you don't have trees, it works as a nice one man tent too with a pair of trekking poles.

Summary

Over-all a pretty sweet rig.

Pros

  • Comfortable (no sticks, rocks or snakes)
  • Stealthy (low impact visuals)
  • Well-made

Cons

  • Spendy
  • Tree straps are innsufficiant

Overall a pretty sweet rig.

I've used it as intended, also when the need arises it makes a pretty decent Bivy on the ground (esp. with hiking poles to keep the bug net high).

I like the Zip model better the the original as it's easier for chair-mode, and much easier entry exit on a cold night (yeah, you know what I mean).

As with all hammocks, it still needs a good under-quilt/over-quilt instead of a sleeping bag, but that's offset by not needing a pad.

I use the optional snake skins which is of major benefit to packing, setup and tear-down. With the snake skins setup takes about 3-minutes (w/o the underquilt) and teardown is about the same. That time includes the rain-fly setup too!

You don't store much gear inside as it would slide to the center, but shoes go into the end well and there's a bivy sack that hangs from the ridgeline taht is great for the nessaceries.

All in all it's a great rig for those that want the flexability of a hammock, but don't want to make or have made a custom setup.

Rating: rated 4 of 5 stars
Source: bought it new
Price Paid: $100+

Summary

I have used the Hennessy since 2010. I have suggested to the manufacturer five relatively easy modifications that would make this very comfortably hammock almost perfect, but none have been implemented.

I did have it on a canoe trip one fall in Upper New York. Very strong rainstorm filled the hammock with a gallon of water, and I and sleeping bag were drenched. If the rain is coming straight down, it is fine, but if blowing sideways, you will get wet. BUT there is any easy fix. I also had it for two 10-day trips along the AT.

Pros

  • Easy setup
  • Light weight
  • Very comfortable for sleep

Cons

  • Very cold during chilling weather
  • Thermal pads slide all over

User since 2010 on canoe trips in upstate NY and on AT, as well as other trips. Most comfortable hammock I've ever used; keeps bugs and critters out, better than military Jungle Hammocks I've used in Vietnam and Panama. Lightweight and strong

Rain fly will collect water in heavy rains no matter how tight you make the lines; a simple fix could be made by mfg to correct this.

When the wind is blowing during a rainstorm, the rain comes in under the rain fly through the side/top bug netting. A very easy fix by the manufacturer would correct this.

Difficult to line up the rain fly with the orientation of the main hammock (because of the asymmetric design);   again there is an easy fix that would correct this.

If you don't have some sturdy trees to tie to (like a beach, meadow, or above tree line in the mountains) you need a simple stand to tie to; when I first saw the hammock on display, there were about two dozen set up under a large parachute, and were all attached to simple stands, but I have not been able to locate where they can be purchased. 

Very cold sleeping off the ground when the OAT is low; Thermal sleep pads would handle this, but they keep sliding all over the place. I think the mfg could fix this with my suggestion, but I've gotten no response from them. They advertise a baffle shroud to go under the hammock for cold weather, but they are not carried in the stores I have visited.

Rating: rated 3.5 of 5 stars

Summary

Great to use, but difficult to set up. Very comfortable and quite rain proof. Good for picky backs.

Pros

  • Comfortable
  • Rain-proof

Cons

  • Tree straps need certain trees
  • Set up is a bit of a pain

I enjoy this hammock for trips to places I'm familiar with. It is very comfortable for sleeping, especially with a pad to help keep in the warmth. I sleep on my sides, and have some solid hips, so the older I get the worst sleeping on hard ground is. A hammock is a great solution, and this one is the best I've found that resembles a tent for comfortable protection. I can even change in it without much difficulty.

The first time I used it was in a rainstorm. I stayed dry, and while I swayed a bit, I didn't sink any. The rain was coming in sideways, and the fly still kept it off completely. I was concerned since the top is open. This also opened it up for great ventilation, didn't get stuffy, and all condensation took itself away on the fly.

Trying to store your gear in it can be difficult, but I put it behind my knees and found that a good way to keep myself at the diagonal necessary for hammocks. This one is made for those under 6 ft. I'm 5 and a half and felt a perfect fit, so If you are 6 ft I'd recommend going up a size.

My biggest problem is setting this thing up. The straps provided only fit certain trees and tensioning all the parts can be complicated. I do not have the Snake Skins, and I'm planning on purchasing them in hopes that this'll make things easier. When packed it takes up a bit more space than I would expect, but it's so much lighter without poles.

Summary

Fantastic design for all types of weather. This hammock does a great job keeping the bugs out. I'm happy to see that it now has a water collection system available.

Pros

  • All-in-one system
  • Very rainproof
  • Versatile

Cons

  • The straps that are included make it hard to find the right tree
  • My Neoair slides all around making it nearly impossible to use for insulation
  • I wish there was some way to secure your sleeping bag or air mattress inside to avoid slipping
  • It would be great to have a way to hang using Nite Ize carabiner

The hammock is a fantastic design. Setup and tear down is simplified using the snake skins. There is very little sway to the hammock during sleep. I have used it in heat and cold and rain. Hammock functions great in the heat as you can get great airflow and its very water resistant.

I did have an issue when I tried to use my air mattress on a cold night. My sleeping bag and mattress slid all around in the hammock and I had only a few minutes of sleep as a result. I would like to be able to suspend the hammock with a Nite Ize carabiner so that I wouldn't have to "mess" with the suspension so much. As it is the right suspension is difficult for me to achieve as I am only 5 feet tall and can't reach high enough on the tree to avoid a sinking hammock. It's no fun to wake up on the ground in the middle of the night.

Overall, a well-constructed hammock (probably the best on the market) that travels well in my backpack. I just wish they'd fix a couple of issues.

G00SE MODERATOR

Your hammock shouldn't be sinking at all. What kind of suspension does it come with? Also the trick to using an air mattress in a hammock is to only 1/2 inflate it. When not using an underquilt, I prefer using a Wenzel foam pad, which stays pretty much in place.
