More to consider...

"Finally, protection from road abrasion cannot be guaranteed by a
materials abrasion resistance alone. A jacket may have panels of
highly abrasion-resistant materials, yet if low-quality stitching joins
those panels and the seams come apart upon impact or during a slide, then
the abrasion resistance of the panels could count for nothing.
Furthermore, an ill-fitting garment may ride up in a slide, contorting
the body and exposing the skin. And the best jacket in the world, left
unzipped and/or unsnapped, won't give riders the protection they pay
for. When it comes to safety, the issues are more complex than just the
abrasion resistance of materials."
