Size Matters Hollow Strap-On Silicone by XR Brands is a silicone improvement device worn inside a harness to add length and girth during partnered sex. The hollow design lets you maintain sensation while delivering increased size, and the realistic texturing creates natural feel for both partners.
Size Matters Hollow Strap-On Silicone by XR Brands combines a realistic silicone shaft with an adjustable harness system designed for secure wear during partnered sex. The hollow interior allows you to slip inside while the solid tip delivers the added length and girth improvement. Unlike basic cock rings, this device wraps around your body rather than sitting at the base, distributing weight evenly across your hips and thighs to prevent fatigue.
The silicone is phthalate-free and body-safe, with careful attention to realistic texturing that creates natural sensations for both partners. The nylon harness adjusts to fit different body types, and the flesh tone mimics natural skin colour. This makes the whole experience feel connected and authentic rather than mechanical.
Before wearing, wash the silicone shaft and harness thoroughly with warm water and mild soap, then dry completely. Slip on the harness like you would shorts, positioning it so the straps sit comfortably across your hips. Adjust the leg straps so they sit flat against your body without bunching or pulling. Insert yourself into the hollow centre—the silicone is flexible enough to accommodate different sizes—and position the shaft so it sits naturally against your body.
Once positioned, adjust all straps for a snug fit that does not cut off circulation but stays completely secure during movement. The hollow design means you remain physically present in the experience, so test-fit without a partner first to find your comfort level. Magnetic Cock Rings offer a different approach using magnetic closure, whereas this harness relies on adjustable straps for a secure, custom fit. A quality silicone-based lubricant reduces friction and increases comfort during longer wear.
This suits couples who want improved size while maintaining physical connection and mutual sensation throughout.
Great if you…Wash the silicone and harness with warm water and mild soap after every use, paying special attention to any textured areas where bacteria can collect. Dry completely with a soft cloth and allow to air dry fully before storage. Store in a cool, dry place away from direct sunlight, which can degrade silicone over time. Keep the harness away from sharp objects and rough surfaces that might snag the nylon.
improvement products come in many styles, each with different strengths and trade-offs. For detailed guidance on how various designs compare and what to expect from hollow versus solid designs, explore our resource on Je Joue Mio Cock Ring for insights on similar body-safe silicone construction and realistic texturing approaches.
The hollow design means you feel the sensations naturally while your partner experiences the added length and girth. Most people find the first fitting takes a few minutes of adjustment—the silicone flexes easily, so positioning is straightforward. The harness sits comfortably on hips without digging in, provided you adjust all straps properly before use.
First-timers often find the realistic texturing more noticeable than expected; the careful detailing creates genuine sensation rather than feeling plastic or artificial. The harness stays completely secure during active use, so you do not need to pause and readjust once you start. Many people wish they had used lubricant from the first experience, as it makes insertion and wear smoother.
Cleaning is straightforward—warm water and mild soap remove all residue, and the non-porous silicone dries quickly. Unlike porous materials, this silicone naturally resists bacteria when cleaned properly. The nylon harness can show wear over years of regular use, but the silicone shaft itself holds up exceptionally well and does not crack, cloud, or discolour with proper storage.
| Design | Material and construction | Best suited to | Key difference |
|---|---|---|---|
| Size Matters Hollow Strap-On Silicone | Phthalate-free silicone with nylon harness; 15.2 cm insertable length, 11.4 cm depth | Couples seeking improvement with ongoing sensation and connection | You remain physically involved inside the hollow shaft while partner experiences added size |
| Solid strap-on dildo | Solid silicone; varies by model from 12–20 cm insertable length | Partners wanting complete control without wearer involvement | Wearer operates the toy externally; no hollow interior means no ongoing sensation for wearer |
| Vibrating improvement ring | Silicone or TPR with battery-powered vibration motor | Users wanting girth addition with added stimulation | Sits at base of penis only; adds vibration but limited length extension compared to full strap-on |
| Penis extension sleeve | Silicone or TPR; slides over entire shaft, 2–5 cm additional girth | Users wanting subtle girth increase for partnered or solo use | Worn without harness; no length addition, girth only; simpler to put on but less stable during vigorous use |
