There's no such thing as a "standard" GorePro - there's a whole bunch of different deniers of fabric they offer; everything from 60d for the Outdoors world on up to whatever the Armacor is (at least 600d). "4s" of abrasion resistance is way more then pretty much every other reinforcement textile out there, although that IS the superfabric patch as an overlay + the standard fabric underneath. Standard 500d cordura evaporates <0.5s in Motocap testing. 1680d "balllistic nylon" overlays don't make it to 2. Of the textiles they've tested so far, the strongest single layer one as far as I know is the S1 fabric Dainese uses.
