It’s indisputable.  Hennessy Hammocks could well be the best in the world.  Light, durable, comfortable and excellently engineered… perfect for warmer areas of the world, right?  Well, you will have seen from the website that ever evolving design solutions are attempting to expand the boundaries of the hammock inhabitable world, from calm low lying areas and comfortable lower latitudes, to where the silent killer reigns supreme…. cold.   So, it was with Hennessy Hammock’s Explorer Ultralite Asym, along with elements of the insulated Superstructure that I found myself in Northern Norway in order to test whether the cold can be defeated by this intruder from the tropics. 
 
 THE TEST
 
CONDITIONS.  The system was tested in the area of 68º 33’ 37.12’’N by 16º 58’.54’’E, east of Harstad, Norway.  Initially mild temperatures prevailed, fluctuating around freezing, which resulted in freezing rain, sleet and snow.  Though this is not the extreme cold that was later encountered, it was far more testing due to the freeze-thaw effect and moisture content of the air which accentuated the cold.  Minimum temperature encountered was - 18ºC (0ºF) still air and estimated at -30ºC (-54ºF) with wind chill.  Maximum precipitation encountered was 7.5cm (3 inches) of snow in 6 hrs.

...CONCLUSION.  The Hennessy Hammock insulation system is capable of supporting a lone traveller in extreme cold weather environments down to -12ºC (10ºF) in the format tested.  This was dependent on the sleeping bag used and a bag with a lower comfort zone than that used in the test will similarly reduce the -12ºC figure.  This figure will also be reduced by: (1) adding insulation to the Under Cover e.g. spare clothing/suitable vegetation, (2) use of the Over Cover, and (3) a solution to cooking which would also heat the living space...However, for those comfortable operating in extreme cold the system works in all respects other than the method in which one can cook, but there must be solutions out there.
