I'm reading this after my first true backpacking test and I can only agree with everything Adam is saying. This is a great setup. My 40° Incubator kept me cozy and warm all 3 nights ranging from 34°-47°F. Not once did it shift out of place even after all my kicking around getting into the sleeping bag. I would occasionally grab the elastic suspension thru my hammock just to see where it was sitting - always nice and tight wrapping around my shoulders.
It worked so well that I marked the positions of the shockcord/line locs with a silver Sharpie, but maybe that could change depending on the hammock setup? Either way, I made a mental note of the foot vs. the head end and how tight each cord was. I learned how to tighten the cord by the WBBB footbox while testing in my back yard.
I love it! Thank you soooo much Adam!
