After getting caught out in a weird diagonal rain that soaked the ends of my hammock, I designed up a different stuff sack. I sent my drawings over to Yama Mountain Gear and they made it up out of dyneema. The new sack splits in half, each half protects the ends off my hammock from wicking in any water that makes it around the edge of my hammock. Please take a look at my first version, and ignore the commentary as I have already decided differently for the second go.
