Quick answer
For most users, a silicone strap-on harness offers better durability and easier cleaning, while TPE provides a softer, more flexible feel at a lower cost. Your choice depends on whether you prioritize longevity or initial comfort.
Material durability and care
Silicone is non-porous and resistant to heat, making it easy to sanitize with boiling water or a dishwasher. It won't degrade over time like TPE, which is porous and requires gentle hand washing with mild soap. TPE can also absorb oils and bacteria, so it's less hygienic for shared use.
TPE harnesses are generally more affordable and have a softer, more flexible feel against the skin. However, they may wear out faster, especially with frequent use or exposure to silicone-based lubricants, which can cause the material to break down.
Comfort and fit
Silicone harnesses often have a firmer structure that holds shape well, providing consistent support during use. They can be adjusted for a secure fit, but some users find them less forgiving than TPE. TPE straps tend to stretch more, offering a snug, custom fit that moves with your body.
The Doc Johnson Body Extensions harnesses combine elastic and premium silicone for a balance of comfort and durability. The BE Strong set includes a 7.5" slim dong, while the BE Bold set features an 8" large dong, both designed for unisex use.
Trade-offs at a glance
- Silicone harness: Non-porous, easy to sanitize, holds shape well, more durable over time. Best if you prioritize hygiene and long-term use.
- TPE harness: Softer, more flexible, lower cost, but porous and less durable. Consider if you want a budget-friendly, soft-feel option for occasional use.
- Body Extensions sets: Combine elastic and silicone for a balanced fit; available with different dong sizes. A good middle ground if you want silicone's durability with some stretch.
