by jiminflfromTarp too narrow...rain gets in during windy stormsI bought the Asym Hyperlite a few weeks ago and took it with me this month on a 8 night canoe trip to the Quetico wilderness in Canada. It stormed 5 of the eight nights with high winds and drenching rain. I had the tarp installed over the hammock exactly as demonstrated in the videos on the product website and in their instructions on the stuff sack. Water got inside the hammock all five nights. Fortunately my sleeping bag has a Goretex shell or I would have been soaked. The asymmetrical tarp is fine in the middle but too narrow at both ends to remain dry during seriously bad weather. I would not recommend using this hammock in wet, windy, rainy locations. If you do, think through what you'll do if you get soaked during the night.

by Iago VfromWhere's the fat?Like the hammock. It does what it says it does. Just for more weight. On the henessy website and here it states that it weights 1 lbs 9 oz. Then when I read the small print, the webbing straps, add 2 oz. However, it's 2 lbs flat on the scale. My scale is accurate. Did they forget to count the fly in their weight estimates?

by backcountry splitboarderfromHennessy Hammocks beat tents 95%/timeI REALLY love the option to just take a Hennessy Hammock, and leave the tent at home. With an REI 2.5 or 3.5, this a-symetrcal hammock to me is more comfortable than a bed, and DEFINITELY more comfortable than the very same pad on the ground in a tent.
Tents do have advantages, however, the simplicity of set up and take down, combined with superior comfort, and a better nights sleep REALLY takes the cake once you get used to using and sleeping in a Hennessy.
Even a smaller, lighter pad, or NO PAD AT ALL is an option for the Hennessy, and it will still be very comfortable, and certainly MORE comfortable than a TENT with a smaller pad, or NO PAD and just a sleeping bag.
Also, it is not as needed to have a pillow in the Hammock, although it might be nice. Once again, in the tent with no pillow, you would be in trouble compared to the hammock.
WIth the new Big Agnes Platinum UL1 and UL2 (the UL2 is the only way to go being only 3 ounces more than the UL1), it is now feasible to carry BOTH a very nice 2 man tent, AND a Hennessy Hammock, which just might save the day when you are challenged to set either one of them up, and don't want to use the Hennessy as a bivy. I personally don't like the bivy concept at all.
SO, for minimalists, it is great to just carry the Hennessy Hammock, and an appropriate thickness sleeping bag for the weather, (or no sleeping bag and just the hammock). Cutting out all that heavy sleeping gear can make your adventure a lot more fun!
On the other hand, there are many options to gear up a bit more, and use a larger ENO or Hennessy brand rain fly instead of the supplied, smaller rain fly, making it a lot more pleasant in rain and severe weather.
I like the Eno gear sling for your pack underneath the hammock, and I also like the option to use an Eno Bug net over the gear sling and the hammock for situations where bugs are truly unruly, although the design of the Hennessy without the external net is pretty good about dealing with mosquitos, etc. Amazon like bugs is what I'm talking about, where a good external net could just save your life!
I like the longer tree straps that Eno makes as well, even though they add a little weight, they are longer, more versatile, stronger, and easier to set up by yourself, especially using screw gate carabiners, which are a must!
I must agree with another reviewer. The only thing is that the WEIGHT SPECS are slightly exaggerated, and I also found it impossible with any combination of parts of this hammock, and and ACCURATE scale to match the given weight specifications. and guess what? the given specs are LESS, of course!
Would appreciate an accurate adjustment of the specs, but that doesn't stop me from being a HUGE fan of the Hennessy Hammock.

by Squatch HunterfromLovin itGot to set it up once and spent the night out in the yard. Its winter and with the supershelter insulation system and thermal sleep shield I was quite cozy even in the wind. More comfortable and roomier than I first imagined. Great product!

by RenegadePilgrimfromAll Kinds of Awesome Sauce!I use this hammock for backpacking. It's super light and contains everything I need to be comfortable (minus under/top quilts) in the woods. It features a bug net and tarp, in addition to the suspension system which I will be upgrading to a lighter version with whoopie slings and cinch buckles.
Since I have started hanging, it is super hard for me to go back to sleeping on the ground. It's not as comfortable and I don't sleep as well as I do in my hammock.

by Dead Mule JohnfromCan't beat hangin'I have just returned from a week in the Boundary Waters and used my HH exclusively. Loved it! This isn't the first time I've used it for camping but it is the first time in a wilderness area. Nothing like hanging on the edge of a lake listening to wolves in the distance and feeling the breeze off the water. Pure camping heaven, man. The Hennessey assymetrical design is total comfort since your lying flat instead of in the banana position. We had two nights of pretty heavy rains and I and my equipment stayed dry and warm. I used the hexagonal fly (separate item) instead of the provided asym fly for addtional coverage, but even with a pretty stiff breeze I had no problems. Packs up easy with snakeskins so I never had to get out from under the fly until I was ready to pack it away. Just doesn't get any better. So go hang.

by onegoneawryfromAmazing minimalist shelter system!Hiked/jogged 160 miles in four days on the NC AT through thunderstorm conditions every day/night. The only time I was dry or comfortable was in this hammock/shelter. The asymmetrical design with proper installation allows for a horizontal laying position that is unlike any other hammock I've been in. This means I could sleep on my side and be extremely comfortable. The side ties on the actual hammock allow it to remain open and roomy while laying inside. I used my thermarest sleeping pad for insulation and it added a great deal of comfort to the overall sleeping position as well. The silnylon tarp when rigged properly holds up extremely well to strong wind and DOWNPOUR conditions. Setup is fast and easy - just ensure an even height with both tree lashings to optimize the asymmetric design function = comfort. Using paracord/550 cord, or line of your choosing, the tarp can be quickly setup to provide instant shelter for a quick lunch on the trail. I did bring 4 titanium 'tent' stakes, which aided in the setup anywhere aspect of the hammock/tarp. These coupled with my trekking poles also allowed me to set this system up on the ground as a tent-like system. I found the quality to be excellent, the weight perfect for a solo hiker, and the ease of setup commendable. I am pretty rough on my gear - I figure if you buy quality gear, it should hold up to some abuse, and this hammock held up extremely well. Caveat: it's an ultralight piece of gear, respect that in the use, and don't overload its capabilities and it should keep up its part of the bargain. Super stoked about its added place in my ultralight arsenal!

by JTCausafromGame ChangerThis product isn't for everyone... Sleeping in a hammock takes getting used to and you'll have to retool your packing style to prepare for not having a vestibule to put your gear in at night, but for people who are shooting for the high mileage days, this is perfect. I can keep my shelter system under two pounds with this hammock and having the capability of hiking until I'm tired and setting up anywhere allows me to make my days as efficient as possible; no more ending my hike before sunset to find a flat spot for a tent.
You'll need to be prepared to insulate your bottom in colder months, so this isn't for winter without an underquilt. During hot summers, it feels a little clammy at first but then you start to feel the material breath underneath you and it feels like an air conditioner, drastically improving my sleep during summer trips. When I do 25-35 miles a day for a week, the ability to set this up, sit in it like a chair to cook, and pass out looking at the stars while protected gives me the boost to keep going hard.
