I am a tarp and bivy user that is looking for the absolute lightest shelter setup for below tree line use in possibly wet conditions.
Recently I started using a medium Neo Air. The thickness of the Neo Air has forced me to place the Neo Air outside my bivy bag to avoid down compression as described here:
Placing the delicate Neo Air outside my bivy requires an additional ground sheet to protect the bivy. The weight of this setup is:
Tarp/Bivy setup
MLD Grace Solo Spectralite 5.6 oz 159g
Polycryo ground cloth 1.5oz 43g
BPL Bivy + stuff sack 7oz 200g
10 pegs 2.8oz 80g
Line 1oz 28g
Total 17.7oz 502g
The weight of The One (no ground sheet, use trekking poles)
The One 16.2oz 459g
Stuff sack 0.4oz 11g
EZC1 1mm line 0.2oz 5.5g
6 pegs 1.7oz 48g
Total 18.5oz 524g
The One is slightly heavier, but MUCH less messy to setup – faster to pitch, no ground sheet that may rip so at a tiny weight penalty it seems like a better combination.
Does anyone have any thoughts regarding my reasoning here?
