H Hair Scare... you could also just go for French lace at the sideburn area , which can be subject to more `pressure` when doing de-bonds, and have Swiss for the rest of it. ... any combination of base materials is possible....I had a really close look at this Fullcap yesterday....I reckon because the hair density is much thinner on this one, the lace feels /`acts`differently and isn`t as physically heavy which is why it`s feeling lighter on the head....the difference between the two laces is fairly subtle as I said before and the main advantage of French is it being more robust in use/wear ......I have a few old Swiss toppers here and feeling the texture of them compared to this French lace system, I honestly was convinced they were the same materials. The first Fullcap was more noticeable especially at the nape area..it felt that little bit thicker and `rougher`in texture, but I`m well-pleased with this one......hope that helps... Paul.
