I bought a Hennesy Hammock at Christmas and have slept outside in it a few times. It definitely needs something underneath to keep it from being so cold. On the down underquilts I've seen, people have commented that they also need some type of water-resistant covering to keep them from getting wet.
So my question is if anyone has made a hammock underquilt out of a synthetic material like Climashield Apex? Does it provide enough warmth, and do so at a weight that's manageable?
For the shell material, would it be possible to use something like Momentum90 on the side that goes against the hammock, but use Silnylon as the outside material of the quilt to protect from rain? Since synthetic doesn't need to be baffled like down, wouldn't it be possible to only "quilt" sparingly to cut down on the amount of thread used?
I've never done this, and I'm fairly new to all the fabrics and materials you guys use, so any guidance is greatly appreciated.
