Now I have recently tested the Hennessy Deep Jungle hammock over at
It is a double bottomed - side entry Hennessy that comes with an
pad/insert to keep warm in winter.
Worked passably well and might be worth a look.
I know I keep warmer in my underquilt, but for kinda cold versus freeze
my ass off cold the pad worked fine.
Of course you could probably insert your own pad in the double bottom.
I will also be using this hammock this spring with my Jacks R Better 10
x 11 tarp. I like the big size and it gives plenty of room for stuff
under the tarp as opposed to the stock hennessy fly
