This is my entire sleeping system packed. Warbonnet Blackbird XL in the light green stuff sack (all hardware inside stuff sack) Cuben fiber tarp with doors and 6 MSR ground hogs in a cuben fiber stuff sack Exped inflatable pillow in red The 2 12L Osprey bags hold my Warbonnet 0-degree down quilt and top-quilt (one each). All my gear for primitive camping in the R40 The same gear in a GL Coyote https://advrider.com/f/threads/the-art-of-packing-light.1333417/page-5 post number 99 details what I take on most rides. Regarding cold spots in a hammock: Thermarest makes a Z-pad that is very light and small. One thing I use them for is to place under my left shoulder while in the hammock as that is the only place I experience a cold spot when using an underquilt.
