Vac-U-Lock Dual Density Silicone Truskyn Colors Set

The Vac-U-Lock Dual Density Silicone Truskyn Colors Set is a complete strap-on system featuring three soft-yet-firm silicone attachments in different sizes and colours, designed for couples exploring penetrative play together. The dual-density material warms to skin temperature, creating realistic sensations without the cold, plastic feel of basic toys.

What's in the box, and what it does

The Vac-U-Lock Dual Density Silicone Truskyn Colors Set from Doc Johnson delivers a complete strap-on system ready for immediate use. Three colour-coded silicone attachments snap securely into the Supreme Harness via the Vac-U-Lock connection—a quick-release mechanism that lets you switch between sizes instantly during a session without removing the harness. The dual-density construction sets this apart: each attachment features a soft, skin-like exterior layered over a firm internal core, delivering realistic feedback while maintaining shape and pressure. Unlike standard cock rings or basic silicone toys that stay rigid and cool, Truskyn material actually warms to match your body temperature within minutes of contact.

The Supreme Harness adjusts to fit most body shapes with straps extending up to 69 inches, and the breakaway threading prevents uncomfortable tugging during energetic movement. The set arrives with everything needed: lubricant, cleaner, storage pouch, and Vac-U-Lock plugs. This means no hunting for compatible parts or additional purchases before your first use.

How to size and wear a silicone cock ring

Begin by choosing the smallest attachment (Pink, 6.5 inches) if you are new to strap-on play. Step into the harness as you would underwear, positioning the ring so it sits comfortably at your groin. Fasten and adjust the straps until they sit snug but not tight—you should be able to fit one finger under the waistband. The harness should feel secure enough that the attachment does not shift during movement, yet loose enough that circulation remains unimpeded. Apply a generous amount of water-based lubricant to both the attachment and your partner's opening before entry. Start slowly and communicate constantly; your partner can signal to switch to a different size if sensation needs to adjust. Many users find Spiked Cock Rings offer external stimulation during similar play, though this set prioritises internal sensation and control.

After your session, remove the harness and gently wash the attachment under warm water with mild soap, paying special attention to grooves and seams. Pat dry with a soft cloth and air-dry completely before snapping the attachment back into storage position. Store the entire set in the included pouch in a cool, dry place away from direct sunlight. The dual-density silicone maintains its shape and firmness indefinitely with proper care, so this investment delivers years of reliable use.

Right fit or not?

Care and storage

Wash all silicone attachments immediately after use with warm water and gentle soap, using a soft cloth or brush to clean any ridges or textured areas. Dry thoroughly with a lint-free cloth and allow to air-dry completely before reassembling or storing. Store the harness separately in a cool, dry place; the included storage pouch works well for the entire set. Keep away from direct sunlight, heat sources, and extreme cold, as temperature swings can affect silicone elasticity over time. Do not use harsh cleaners, alcohol, or bleach. With this routine, your set will maintain its texture and firmness for years.

Couples new to strap-on play often wonder about positioning, comfort, and what realistic sensations actually feel like during use. Our detailed guide at Cock Rings covers common questions and practical tips. Exploring your options before purchase always leads to more confident, comfortable play.

What to expect

First-time users often underestimate how quickly the dual-density silicone warms to body temperature—usually within two to three minutes of contact. This warmth creates a startling shift in sensation from cold material to something that genuinely mimics living tissue. Many people expect the attachment to feel rigid, but the firm core is made to yield slightly under pressure while maintaining shape, delivering feedback that feels considerably more realistic than solid silicone.

The Vac-U-Lock connection is reliable, but some users find the snap mechanism requires a firm, deliberate twist to seat properly the first few times. Once you understand the motion, changing attachments becomes instinctive. The harness will shift slightly during vigorous movement if straps are too loose, so spending time adjusting fit before play begins pays dividends; many couples tighten adjustable straps by one notch during initial sessions, then ease them slightly once they understand their comfort threshold.

Cleaning is straightforward—warm soapy water and air-drying work perfectly—but silicone does trap residue in textured areas if you rush the process. Five extra minutes under running water and a soft brush prevents buildup and keeps the attachments feeling fresh. The set does require dedicated storage space; it is not pocket-sized or ultra-portable, so plan accordingly if travel is frequent.

Most couples report that having three sizes reduces the pressure to pick one "perfect" option beforehand. The ability to try the smallest attachment first, assess sensation and comfort, then progress or change mid-session without stopping removes a common source of anxiety. Users who struggle tend to own the set but use only one attachment repeatedly, suggesting they chose poorly initially; starting with the Pink (6.5 inches) almost always works better than jumping to the Purple.
