4Season Expedition Zip
4Season Expedition Zip
This 4Season system has advantages when you find yourself in colder weather than expected because it can be adjusted to a wide range of temperature conditions without adding weight or bulk.
With just the oversize open cell foam pad, most people are comfortable down to about 40 F / 4 C. Adding the space blanket under the pad should take you down to below freezing. The space blanket can be placed above or below the pad depending on the temperature, humidity and what works best for you.
If you have been wearing a jacket during the day, spread it out on top of the open cell foam pad or anything else in your pack that has insulation value such as extra clothing, towel, hat or socks to get you down into the twenties, maybe even lower. The pad can be stowed in the compression sack when not needed or left at home. If it’s a relatively warm night, you may want to keep the pad in the compression sack and let the trapped air space between the two layers keep you cozy.
Also, we have included a 7” / 18 cm diameter compression sack. This allows the hammock and the 40 inch / 100 cm wide insulation pad to be folded in half lengthwise, rolled up and easily slid into the compression sack, pushed down and closed with a drawstring. Finally, the cap is pulled over the top of the compression sack and the straps tightened to about 16” / 40 cm in length.
Tom knew that the people of Central America sleep diagonally in their hammocks. So, with that knowledge, he changed the shape of his hammock into his patented asymmetrical design which lets you lie level on the diagonal with excellent support under your lower back and knees.
Because tree spacing is always different, the curve of a hammock is always different. The patented structural ridge line ensures the same shape every time you set up your hammock. This is the first time in history that you have the exact same comfortable bed every night and a perfect setup every time
Asymmetrical hammock shape (US Patent US6865757B2); Structural ridge line patent (US patent US20090165205A1) Also patented in the UK, EU, AUS/NZ, and Canada.

Now you can mix and match hammock parts for your specific needs. As you will see, sometimes there is only a small price increase to get exactly what you want instead of buying more than you need.
FREE LONGER WEBBING STRAPS: Our stock webbing strap is 42" / 107cm which is fine for trees up to 14" / 36cm in diameter. Now you can get a free upgrade to longer 72" / 183 cm straps for trees up to 24" / 60cm in diameter or 96" / 244cm straps for trees up to 36" / 91cm in diameter.
WHAT'S INCLUDED: The 4Season Expedition comes complete with attached mosquito netting, detachable rain fly, support ropes, and compression sack with set up instructions on back. Hennessy Hammock also provides complimentary standard 42" / 107 cm long "Tree Hugger" webbing straps to protect the bark of trees. Because these accessory webbing straps are complimentary, they are weighed separately from the hammock.
The 4Season Expedition also includes an oversized 30" / 76cm wide open-cell foam pad, and a heat-reflecting space blanket.
