The Vac-U-Lock Dual Density Silicone Truskyn Colors Set from Doc Johnson is a complete strap-on system featuring three dual-density silicone attachments in vibrant colors. Each attachment uses Truskyn silicone technology with a soft exterior and firm core that warms to body temperature. The set includes a Supreme Harness with adjustable straps and three different-sized attachments for varied experiences.
The Vac-U-Lock system uses a snap-in connection that lets you switch between the three colored attachments instantly during play. The dual density silicone feels incredibly realistic - soft on the outside but with a firm core that delivers satisfying pressure. The Supreme Harness adjusts to fit most body types and keeps everything secure during intense sessions. For enhanced comfort, pair with our male pleasure accessories for complete satisfaction.
What sets this apart from basic strap-on sets is the Truskyn material technology that actually warms to match your body temperature, creating sensations that feel surprisingly natural rather than cold and artificial.
| Style/Type | Best For | What Makes It Different |
|---|---|---|
| Vac-U-Lock Colors Set | Couples wanting variety and realism | Three sizes, dual density, instant attachment changes |
| Basic Strap-On | First-time couples | Single size, simpler design, lower cost |
| Premium Realistic | Experienced couples | Ultra-detailed texture, single high-end attachment |
Couples exploring strap-on play: The three different sizes let you start smaller and work up to more intense sensations. Quality materials and secure harness make it perfect for beginners who want something that will last. Consider adding silicone-based lubricant for the smoothest experience possible.
Experienced players wanting variety: Having three different attachments means you can change things up mid-session or match your mood to the right size and color combination.
This set gives you everything you need without having to buy separate pieces. The dual density construction feels incredible - way more realistic than standard silicone. Doc Johnson built this to last, and the Vac-U-Lock system means you can add more attachments later. It is the difference between a toy that feels like plastic and one that actually feels like the real thing.
Real experience:
I was amazed how quickly the attachments warm up to body temperature. The Purple 8" felt intense but not overwhelming, while the Blue 7" became my go-to for longer sessions. The harness stayed put even during our most energetic moments, and switching between sizes mid-play was incredibly smooth.
What blew me away was how realistic the dual density construction feels. The soft outer layer gives way to firm pressure exactly like you would expect. The visual variety of having three colors added a playful element that kept things exciting, and my partner loved being able to choose based on mood.
