The Silk Base is constructed with a layer of lace and pure silk fabric on the top of the cap. The knots of the hairs are hand-sewn under the silk base, so the knots are concealed between the layers. This technique of injecting the hairs through the silk to conceal them, provides the illusion that the hair is coming from your own scalp when you wear it, making the knots 100% invisible. 

So far, the Silk Base is considered to provide the most realistic scalp the market has to offer. You don't need to bleach the knots or use any concealer to mask the knots at the parting like a lace base may need. The Silk Base looks completely natural and realistic. 

PROs

Realistic Looking: Silk Base toppers can give you the appearance of having a scalp that looks like your own. A Silk Base is the most realistic topper base on the market today. With a Silk Base, you don't need to hide or camouflage the knots when you part your topper!
Styling Versatility: The Silk Base offers versatile styling options as you can part your silk topper any direction.

CONs

Difficulty Laying Flat: Due to the multiple layers in a Silk Base topper, Silk Base hair toppers are not as easy to lay flat on the head. Silk Bases may also encounter slight bulkiness on the crown. Due to this, Silk Bases usually take a little extra work to lay flat compared to other bases.
Breathability: Due to its unique layered construction, the Silk Base can lack breathability compared to lace and mono bases. Silk Bases may also be slightly warmer to wear during the summer than the other two bases.
