Camping, Hennessy Hammock HH Expedition zip with the 30D monsoon rainfly March 5, 2013 pmullen Leave a comment Click the link for more Hennessy Hammock Hennessy Hammock Expedition Zip with the HH Monsoon 30D Rainfly with side panels. First setup was the backyard right off the start I noticed the rainfly was going to give more room underneath the hammock. The side panels will definitely block wind and rain / snow. All tie out points include shock cord and also rope with a stow away pocket for storage of the cords. The tarp weighing 18 oz and you can wrap the hammock and rain fly in the snake skins just as if it was still the regular rain fly.
