Hyper Soft Silicone (HSS)

Hyper Soft Silicone (HSS) is a proprietary silicone construction developed by Irokebijin to achieve a more natural, flesh-like feel than traditional single-density silicone dolls. Rather than relying on one uniform silicone hardness throughout the body, HSS uses a dual-density approach. A softer, more elastic silicone layer is applied to the outer surface of the body, while a higher-density silicone core maintains structural support around the skeleton.

The result is improved surface compression, softer touch, and more realistic rebound in high-contact areas such as the bust, hips, thighs, and buttocks, without sacrificing durability or pose stability. HSS is still platinum-cured silicone, not TPE and not gel-filled, but engineered to reduce the firmness typically associated with silicone dolls. As with all ultra-soft silicone formulations, careful handling is recommended to preserve surface integrity over time.
