I have a Yukon hammock I picked up on Woot. Does anyone know what type and weight of fabric this is? I think it is "parachute nylon," but I'm not sure what that means. Is it nylon taffeta? What weight?

This hammock has sold me on the idea of a simple, single layer netless hammock for the winter, but it is pretty floppy and stretchy. I am thinking about either a Simply Light Designs Streamliner or a Dream Hammocks Freebird. SLD has a 1.6 and a 1.9 nylon ripstop, while Dream Hammocks has a 1.8 nylon taffeta, a 1.8 polyester taffeta and a 1.9 nylon ripstop. I am 5'11", #175. I don't have enough experience with fabrics to decide between them. My other hammock is a 1.1 double layer WBBB that I really like, but I was looking for something lighter and easier for winter. I appreciate any input you might be able to give. Happy Thanksgiving!
