For rainy conditions, you can drop the bivy and increase the size of the tarp and achieve both a dryer set-up and net decrease in weight. (Even more if the tarp is constructed from cuben.) Your bag already has a great DWR if cowboy camping (my preferred choice) that eliminates the need for a bivy in dry conditions:Buford wrote:Tarp+big bivy
Katabatic Sawatch
Katabatic: We use this ultralight Pertex Quantum as the shell fabric on our sleeping bags. Pertex Quantum fabric is down proof, very breathable, and features the best DWR treatment we have seen.
My list:
DIY 25 degree quilt (15oz 900FP + 6oz M90 shell/liner)
DIY 9'x8' cat-cut tarp-tent
DIY 35L pack - just bought some 210 Dyneema ($27/sq yd!) to copy present Sil version
48" cut-down RidgeRest (folded & also used as pack pad + pseudo frame)
Ursack - I've been staying out of canister required areas or traverse during the day
