The Vibrating Dual Density Ultraskyn Set by Doc Johnson is a complete strap-on system featuring three realistic attachments, an adjustable harness, a remote-controlled vibrating plug, and a suction cup base. It suits couples exploring strap-on play together or anyone wanting hands-free solo options with realistic sensations and vibration intensity.
The Vibrating Dual Density Ultraskyn Set by Doc Johnson delivers everything needed for strap-on exploration in one package. The system centres on three separately sized ULTRASKYN attachments built using dual density technology—a soft outer layer that warms to skin temperature paired with a firmer inner core recreating realistic sensation. Most vibrators and strap-on systems require separate purchases for harness, attachments, and vibration options; this set eliminates that fragmentation by including each component alongside care products.
The Vac-U-Lock connection system lets you swap attachments without removing the harness, and the vibrating plug transforms any attachment into a powered experience. The adjustable harness fits most body types, whilst the suction cup base opens hands-free play possibilities for solo use or partnered sessions without wearing the harness.
Before first use, clean all pieces thoroughly with warm water and the included antibacterial cleanser, then dry completely. Apply water-based lubricant generously to the attachment and the receiving partner's entrance; do not use silicone lubricant as it can degrade ULTRASKYN. Insert the attachment carefully, beginning with the slimmest option if you are new to strap-on play, and allow a few minutes for the material to warm and stretch comfortably.
Start vibration on a lower setting and increase intensity gradually once insertion feels secure and comfortable. The remote control reaches several metres, useful for hands-free play or when your partner operates the vibration. After each session, clean all pieces immediately with warm water and mild soap; pat dry and store in the included pouch away from direct sunlight. For extended or intense sessions, reference guidance on Premium Prostate Vibrators to understand how different vibration patterns affect tissue and recovery.
This system works best for couples or individuals wanting multiple attachment sizes and luxury prostate vibrators in one purchase.
Great if you…Clean all ULTRASKYN attachments and the harness after each session using warm water and the included antibacterial toy cleanser; avoid harsh scrubbing that might damage the material. Pat dry completely with a soft cloth, then store in the included pouch in a cool, dark place away from direct sunlight or extreme heat, which can warp the material. The suction cup base can be wiped clean with a damp cloth and dried before storage. Replace the remote's batteries every 6–12 months depending on use frequency.
Strap-on systems offer couples intimacy possibilities that fixed toys cannot, whilst the addition of vibration and multiple sizes deepens exploration across sessions and preferences. Understanding how different attachment shapes and vibration intensities affect sensation helps both partners communicate about comfort and desire.

The dual density ULTRASKYN material feels distinctly more lifelike than silicone or rubber alternatives because the soft exterior layer allows subtle movement whilst the firm core provides structure and support. First-time users often find the initial insertion takes longer than expected—five to ten minutes of careful progression is normal as the material stretches and warms. The sensation improves noticeably once insertion feels comfortable, since the warmth of body contact improves the realistic feel.
Vibration with strap-on play works differently than with external vibrators because the attachment sits inside rather than against the clitoris or prostate. The vibration resonates through the inserted piece and surrounding tissue, creating broader sensations than pinpoint stimulation. Most people find starting on lower vibration settings and building up works better than beginning at maximum intensity.
Cleaning is straightforward since ULTRASKYN resists odour and discolouration better than porous materials, though immediate washing after use extends material lifespan significantly. The suction cup base loses grip gradually over months of use as the silicone ages; replacement suction cups are inexpensive and extend the product's life. The harness stitching remains durable across extended use when stored dry and away from sunlight.
Most people who return strap-on systems cite sizing mismatch rather than material or design issues—starting with the slimmest attachment ensures you do not abandon the whole set because of initial discomfort. Partners who communicate about intensity, pace, and comfort throughout sessions experience more consistent satisfaction across repeat use.
