Hi Landon.. it`s French lace though I was convinced when I got it [ this is my 2nd Fullcap] that it was Swiss...even asked John to check with the factory..this one feels a much smoother texture....the first one was/is definitely coarser....this one is much smoother and very like Swiss...... another wearer posted technical details of various laces a while back but I can`t remember which thread it`s on.....maybe I just got a different grade of lace... I`m not sure...I`m mystified ! Anyway, the base has no real bearing on the style as such...the density/ventilation are the main things.....the only possible downside of getting a lower-ish density is that when it begins to age/wear and possibly shed, you haven`t much to `fall back on` ...... 60% is still quite good for allowing scalp show-through,while allowing a bit of `margin` if/when shedding eventually begins...regards, Paul.
