Hi,
I am thinking about a hammock design that can be used as a bivy when trees are not available. I am considering a three-layer design where the bottom layer is slightly larger than the middle layer to create an insulating air pocket, and I hope that this will be enough for me to let the underquilt stay at home? There will be a velcro opening between the bottom and middle layer so I can slip in a sleeping pad when used on the ground.
Middle layer is low-weight parashute nylon, and top is breathable PU-coated nylon with a bug-net "window".
The design is for use under tarp both as bivy and as hammock.
Please see attached drawing.
I am considering the following fabrics:
Top:
Nylon, PU-coated, breathable, 100den, 80g/sqm
Middle:
Ripstop parachute nylon, 100% nylon, 40g/sqm
Bottom:
Groundsheet, Nylon, PU-coated, 90 g/sqm
Please give me your input on fabric, design and what else comes to mind. This is by far my biggest DIY project, so I would like as much input as possible before spending my hard earned money.
Thanks,
Christian
