My recollection of the Ascensionist (and ReadyMix before it) is that the fabric is very tightly woven; much more so that Dryskin. It's also thinner, with a much lighter 'fluff' on the inner face, again, compared to Dryskin.
The ReadyMix/Ascensionist are, IMHO, very robust windshells, trading insulation for air permeability. Dryskin offers more a little more static insulation, but is more air permeable. Pick to suit your operating point...
