BioFlex Bionic Soft Touch™

Q: How is BioFlex different from standard TPE?

Standard TPE uses a single uniform layer. BioFlex uses a two-layer structure that mimics fat and muscle distribution — delivering softer, warmer, more elastic contact, especially in breasts and buttocks. See the comparison table on this page for details.

Q: Can I choose soft breasts or standard firmness?

Yes. When ordering, you can select Jelly Breasts™ (soft) for maximum sag and bounce, or standard firmness for more structural support. Watch the comparison videos in the Jelly Breasts™ section on this page to see the difference. For other custom options, contact support@evolova.com or Telegram @Evolova001.

Overview

BioFlex is Evolova's answer to the uncanny stiffness of traditional doll materials.

We engineered a bionic soft-touch layer that replicates how human skin feels under pressure — not just on the surface, but in how tissue beneath responds. The result is the most lifelike tactile experience in our lineup, applied to every Jelly Breasts™ and Jelly Buttocks™ build.

Whether you're a first-time buyer or a seasoned collector, BioFlex is what makes an Evolova torso feel fundamentally different from static alternatives.

BioFlex Bionic Soft Touch™

A two-layer TPE structure that replicates how real skin feels — not just on the surface, but beneath.

Traditional doll materials feel stiff because they use a single uniform layer. BioFlex Skin™ solves that with a dual-density TPE architecture — a soft, skin-like outer layer over an engineered inner core that mimics how fat and muscle distribute beneath human skin.

How the two layers work

The outer layer delivers warmth, softness, and realistic stretch. The inner layer provides structural support and zone-specific firmness — softer in breasts and buttocks, firmer at the torso and limbs. Together they create contact that feels alive, not plastic.

This is the foundation behind Jelly Breasts™ and Jelly Buttocks™ — Evolova's most requested tactile features across our premium lineup.

BioFlex Skin™ vs Standard TPE

Not all TPE is created equal — here's what Evolova's engineered layering adds.

BioFlex Skin™ is Evolova's engineered two-layer TPE — not basic off-the-shelf material. This chart shows what that means in practice.

Factor	BioFlex Skin™	Standard TPE
Structure	Two-layer design mimics skin + underlying tissue	Single uniform layer throughout
Softness	Ultra-soft outer layer with tunable inner density	Firmer, less variation between body zones
Breasts & buttocks	Jelly Breasts™ / Jelly Buttocks™ — natural sag and bounce	Flatter feel; less realistic tissue movement
Warmth & touch	Warmer, more skin-like tactile response	Cooler initial feel; less lifelike rebound
Stretch	High elasticity with zone-specific firmness	Moderate stretch; uniform resistance
Aging resistance	Maintains softness longer with proper care	More prone to surface hardening over time
Cleaning	IPX7 waterproof — immerse after powering off	Varies by manufacturer; often wipe-only
Best suited for	Daily interactive use — touch, poseability, immersion	Budget builds prioritizing price over feel

Jelly Breasts™

Choose soft Jelly Breasts™ or standard firmness — watch the comparison above.

Both breast firmness options are available when you order. Compare natural movement side by side.

Jelly Breasts™ — Soft

Standard Firmness

Evolova offers two breast firmness options when you order: ultra-soft Jelly Breasts™ with natural sag and bounce, or standard firmness for a more supported feel. Both use BioFlex Skin™ layering — the difference is how much give and movement you want.

Soft vs standard — which is right for you?

Jelly Breasts™ (Soft): Maximum realism — natural sag, deep give, and lifelike rebound. Best if touch and immersion are your priority.
Standard Firmness: More structural support with less movement. Best if you prefer a firmer, more held shape.

Our flagship soft-breast showcase is Kim 2.0 — the #1 best seller for collectors who prioritize touch.

Jelly Buttocks™

Impressive curves with unprecedented softness — firmness and flexibility that feel alive.

Jelly Buttocks blend aesthetic curves with tactile realism. Gentle pressure reveals high elasticity and adaptability — the kind of firm-yet-yielding response you'd expect from real tissue, not a hard shell.

Designed for immersion

Whether you're exploring different body types or want maximum plushness, BioFlex-engineered buttocks deliver consistent softness across our lineup. Fuller builds like Celesta 2.0 showcase Jelly Buttocks™ at their most immersive.

Softness That Lasts

Superior aging resistance without sacrificing the touch you bought it for.

BioFlex maintains its signature softness while resisting surface aging better than conventional single-layer TPE. Even with regular use, Jelly Breasts and Jelly Buttocks retain their original elasticity and tactile feel.
