Silicone, or hydrogel, this production process is more demanding, therefore the general price are going to be costlier than silk-filled breastplate. Silicone filled feel excellent , my office features a pair of D cups, when free time i will be able to use to play, pinching the texture and therefore the real breast. And wear walking, will naturally sway, extremely real, can do to fake.
Silk cotton, the breast forms using kapok filling are going to be much lighter than silicone filling, for instance , an equivalent C cup breastplate, silk weighs 2kg, silicone are going to be about 3kg. If you're wearing an extended time I suggest you select silk filling, because relatively light isn't easy to fatigue.
