Rated 5 out of 5 by from Life Saver I spent the summer living in the Teton Valley of Eastern Idaho filled with rain storms, bugs, anything you could think of, even snow. While the rest of my coworkers decided on tents, I decided to stay in this hammock. Jealousy filled the workplace as I was continually dry, easy set up/take down, and the comfortability was unbeatable. Amazing product! Unfortunately I had a deer run inbetween the hammock and the tree I tied it off to and caused the cord to snap. However, because of the stretchability of the cord it didn't affect the hammock at all and it's a simple repair. Excellent product! Buy it.

Rated 5 out of 5 by from Can'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.

Rated 5 out of 5 by from All 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.

Rated 5 out of 5 by from Game Changer This 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.

Rated 2 out of 5 by from Tarp too narrow...rain gets in during windy storms I 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.

Rated 5 out of 5 by from Amazing 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!

Rated 5 out of 5 by from Lovin it Got 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!

Rated 4 out of 5 by from Where'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?

Also, what is the difference exactly between this 200+ dollar hammock and a 45 dollar hammock? What, essentially, am I paying for?

Asked by: Shaught
Mostly, you are paying for features and usable conditions. An inexpensive hammock will not have a rainfly, and a bug shield. Both of these are vital for using the hammock as a backcountry camping hammock. If you just want to take a nap in your house or backyard on a sunny day, the 40 dollar hammock is your best bet. If you are looking to replace your tent, go with the more expensive one.

Never used a hammock before. It sounds like this product entirely removes the need for a tent(obviously), sleeping pad AND sleeping bag. Is that the case? All you need for shelter is the hammock and possibly a "quilt?" is that just any blanket?

Asked by: Shaught
You will find that in almost all conditions, you will need a pad as well. Because you never warm up the air below you, and you crush the insulation in your sleeping bag you are directly exposed to the air below you. This means you will be cold if the outside air tempature at night drops below your personal comfortable tempature.

Asked by: Trek newbie
While this hammock will be long enough for you, it has a maximum weight capacity of 200 pounds. We do not recommend taking this into the backcountry. The Hennessy Hammock Explorer Ultralight Asym Classic Hammock has a max weight capacity of 250 pounds and is a better choice. https://www.rei.com/product/721900/hennessy-hammock-explorer-ultralight-asym-classic-hammock

Can you enter on either side of this hammock, wondering if I need a left or right zip sleeping bag?

Asked by: Kathy Levesque
The fly does only open on one side, but since you can reverse the hammock (flip it around) the opening can be on either side. Get any sleeping bag you like!

Asked by: kupuna
Performance results for this hammock (and any shelter for that matter) are influenced by where and how you pitch your shelter. So long as you're pitching this hammock correctly you should expect to stay dry even in the wettest of Hawaii's climates.
