I'm working on plans for a DIY down underquilt. I'm a little confused about the RSBTR fabric options as there doesn't seem to be a lot of description on the website (at least I haven't been able to find the information I'm looking for).

Can anyone tell me if the 1.0 HyperD fabric is taffeta or ripstop?

What is the difference between the 1.0 HyperD and the 1.1 Ripstop?

Lastly does anyone have closeup pictures of these two fabrics that show the ripstop pattern?

TIA
