Who said hammocks give that claustrophobic feeling? 

“It’s a tent…It’s a hammock…It’s a Chair… It’s a lounger… It’s Super Shelter!”

The Hennessy Hammock Deep Jungle is an EXCELLENT sleep system. It is very clear that R&D was very well done before this product became available to consumers. An asymmetrical design, it is very easy to lie almost completely flat when in this hammock. Hennessy Hammocks has grown to have a devoted following of long-distance hikers, people with back problems, and the everyday hiker!

Testing Conditions

I have used this hammock on several backpacking trips, from summer into late autumn, and spring in northern Maine, Virginia, West Virginia, and Maryland. I have also slept in this hammock at home, and on day hikes many times.

Temperature ranges have varied from about 90°F+ area, to under 30°F. Wind has varied from still nights to very breezy, 30mph winds in November, below freezing. Testing has occurred from Summer 2014 through Spring 2015.

The Hammock

The HH Deep Jungle is so rich with features, the manufacturer has really gone to great lengths to comfort the consumer. The hammock's simplicity is also part of the success of the product; lightning quick, dry setup time, great packability... I have found all components to be very well constructed, and equally well though out. 

The bottom fabric of the hammock is very spacious, with separate attachment points (bungee guy lines) to keep it open.

Two-way zippers allow one to easily get in, out, and secure the bug netting, which doesn’t allow ANY critters in!



The netting can also be folded and secured out of the way, allowing an open view on mild days and nights.

I personally find this particular hammock so comfortable I have made this my primary shelter as long as trees are around. The only disadvantages that I can even think of are synonymous with all hammock systems; ie. not having a place to change clothes, a place to spend substantial downtime during storms, etc. It is arguable that the hammock makes a great seat, and area to cook, etc. however the footprint for spreading out gear in a storm is limited.

The Rainfly

HH has given the consumer countless options using a rainfly with this hammock system. Since the consumer has the option to attach the rainflies directly to the anchor points, ventilation is 100% customizable. There are factory attachment points on the ridgeline of the hammock, which are adjustable using Prusik knots.

The rainflies can also be externally attached to the anchor points, allowing different ways of configuration for rain/wind coverage.

Construction for both the hex fly and the asymmetric are very high quality, and show no wear from use. All of the nylon line is very easy to use/work with, and has built in pockets on the underside for storage.


Pockets are at every line attachment on both rainflies.

It is recommended to use a larger footprint rainfly for inclement weather, or cold weather use. Aside from mild weather, the Hex rainfly was my go-to.

The Webbing Straps

I have been using the 1.5" x 72" webbing straps, and have found in the Mid-Atlantic area that this can be problematic when finding the perfect site. Although I greatly prefer to sleep far away from others, sometimes that perfect spot has a very large old tree. They are extremely durable and well made, and closely resemble the material used for automobile seatbelts.

Experimenting with a friend’s carabiner/rappelling ring system; easy, but a lot of unnecessary weight. Note: Hennessey Hammocks does not recommend anything other than standard lashing to the webbing straps.

The DoubleBubble Insulation Pad

Claimed to reflect 97% of body heat back to the sleeper, this pad did a very good job keeping me warm down to about 40°F. Like the asymmetric design of the hammock, the pad installs one way, with two attached lines and clips to keep the pad adjusted where you need it to be. It is a little cumbersome, but isn’t all insulation?

For those without overnight hammock experience, it is crucial to understand that insulating underneath your body has paramount importance! Like conduction robs body heat when ground sleeping with too little insulation, air circulating under a hammock sleeper steals warmth via convection.

The Snakeskins

This is an ingenious method for storing a hammock! It is an easy way to keep the hammock clean, dry, and organized!

Having a spinal injury, this is a superb way to sleep if traditional ground shelters are no longer ideal. Hammock systems give opportunities to hikers like never before, allowing one to have a much larger canvas for resting locations. One can be elevated from rocky, uneven, wet, snow covered, bug covered ground with no worries!


Not a bad place to get some fresh air!
