It's a base/hair combo that I came across.
I bet it is an old technology repackaged/remarketed as a new concept. Here is what it claims:
(Super Fine Swiss lace front)Each hair is indvidually drawn through from the ventilated layer through the extra light silk mono one hair strand at a time. It is the only system where hair will not knot or tangle. The hair looks like it is coming right from your own scalp. The Super Silk Hair System combines all the elements we want in a hair system; a perfect hairline, a real appearance hair is growing right from your scalp (No KNOTS, NONE), fully breathable, light weight and durable

It sounds like the i-lace but with an SFS front.

Are these types of systems better to wear?
