No they aren't. He said leathers have superior abrasion protection to textiles. He then said some textiles have adequate abrasion protection.FYI the two sentences above are contradictory.
You've already stated that all quality leathers offer the best abrasion protection; Craig agreed with you. Craig then said that there are textiles that offer abrasion protection that is less than or equal to some leathers, and that abrasion protection on those textiles is more than adequate for many crashes. He never said that leathers offered inadequate abrasion protection which would have made the sentence illogical.
Those aren't contradictory; if anything they're complimentary in the context of this thread.
