Dale, your first picture is close, but my fabric has more of a cross-hatched pattern instead of a rectangular hole pattern (for lack of better words).
I looked at the tag, and this is the info I have - RN: 51884, CUT: 41546, STY: 44440F8 <---that's a zero before the F, not an O
And two other sets of numbers with no identifying text: 888052763766 and 0467238961
Anyway, I've had no luck on trailspace or google. It insulates really well, so I think it might be Cap 3, but if someone is able to use this info to find out for sure, that would be cool.
