Irontech Doll Breast & Butt Filling Options

Irontech offers different fillings for the breasts and butt to change how soft, firm, or bouncy they feel.

The outer silicone or TPE stays the same. What changes is the material inside.

AquaBounce

Best for: More bounce and rebound

AquaBounce feels soft but also springs back quickly after being squeezed.

Compared with gel, it feels more elastic and less soft or “mushy.”

AquaBounce is currently available for selected Irontech Oriental Series dolls.

AquaBounce Breasts and Butts

Gel & Softer Gel

Best for: A softer breast or butt

Gel filling makes the breasts and butt softer and allows more natural movement when squeezed or moved.

Softer Gel is the softer version if you want the softest feel available.

Gel and Softer Gel are available on many Irontech silicone and TPE dolls.

Gel Breast vs. Softer Gel Breast

Solid Breast

Best for: Firmer breasts and better shape retention

Solid breasts feel firmer and hold their shape better.

They are a good choice if you prefer a fuller, more upright breast shape or mainly use the doll for photography and display.

Hollow Breast

Best for: Lower weight

Hollow breasts have an air-filled cavity instead of a heavier filling.

They remain soft while reducing some of the doll's weight.

Hollow Breast is available for Irontech TPE dolls only.

Which Filling Should You Choose?

If you want more bounce, choose AquaBounce.

If you want softer breasts or butt, choose Gel or Softer Gel.

If you want firmer breasts that keep their shape, choose Solid Breast.

If you want lighter breasts on a TPE doll, choose Hollow Breast.

Available options vary between Irontech doll bodies, so always check the customization options on the individual doll page before ordering.
