Made a couple of regular size bivysacks with the top of waterproof breathable fabric from RBTR. 10Denier. Bottom of more durable 30d with a not so slippery Sil/PU blend coating.

For the first BPL reader that wants one, I have a slight second (has some sharpie marks inside the top fabric) for $25 off. ($161 shipped in USA). Contact thru PM for this one.
