Read Tom’s recent posts in the Forums on urethane coatings and 1050 denier ballistic nylon vs. 1680 denier ballistic nylon.
“Yea pretty close: the 1680 “ballistic” is woven of a single yarn of 1680 denier nylon, while the 1050 domestic fabric is woven of two 1050 denier yarns. Both fabrics are of comparable thickness, and in terms of flexibility or “hand” as we call the stiffness, both can be finished to be either soft of firm.
Anyway, this explains why they are called by different names. Why they perform differently is less clear to me. I do know that the 1680 can look crappy after only a few months use. I will ask my fabric guru John Ball when next I see him to explain more, and I will post again here soon!”
