I don't like the plasticy feel of the 1.1oz ripstop (DWR) I planned to use for an inner shell. Now I'm looking at nobul1 (AKA 8D or EightD) and M90T.
My decision is stalled because I've heard that 8D had some issues with leaking down and the M90 will cost more...I could go either way at this point. I'm also considering Impetus 1.0 but I haven't heard as much about it. Pertex is possible too but I don't it as a contender.
Cost plays a minor role but the differences aren't very dramatic at 4 yards shipped: Nobul1 $36, Impetus $40 and M90T is $47.
So, Impetus, Nobul1 or M90T for an inner shell?
EDIT: decided to just go with Nobul1...will post results.
