When looking for gear that delivers both base compression and low-hanging ball isolation, standard cock rings often fall short. The X-Stretch Unit-X Sling by OXBALLS combines a low-profile cocksling design with an extended rubbery ball stretcher to hold your package snugly in place.
Modeled after the popular Unit-X, the X-Stretch edition adds an extra inch of stretchy rubberized base that actively pushes your sack down and away from the body while maintaining a firm grip around the base of the shaft.

What Makes the X-Stretch Unit-X Sling Unique?
Unlike traditional round rings that press flat against the pubic bone, the X-Stretch Unit-X Sling utilizes an ergonomic, contoured shape that wraps around your anatomy like a second skin. The interior chamber features a raised retention ring near the lower opening that captures high-and-tight testicles and keeps them tugged down into the stretchy lower pouch.
Manufactured from OXBALLS’ proprietary FLEXtpr blend, this accessory delivers the plush feel of silicone combined with superior tensile stretch and memory recovery. Whether you are wearing it for enhanced erection firmness, extended ball stretching, or as a bulge booster under gear, it provides support without excessive bulk.
5 Essential Benefits of the X-Stretch Unit-X Sling
1. Extended Low-Hanging Ball Stretcher Base
The primary upgrade of the X-Stretch Unit-X Sling over basic slings is its extended base structure. Adding an extra inch of pliable FLEXtpr rubber, the lower chamber gently pulls your testicles down and away from your torso, preventing high-and-tight retraction during intense play.
2. Inner Retention Ring for Secure Fit
Inside the lower chamber lies a specialized internal ring designed to lock your sack in place. Once your testicles are threaded through, this internal barrier keeps them low without slipping back up, regardless of movement or body position.
3. Slim, Low-Profile Ergonomic Design
Bulky gear can feel restrictive or uncomfortable under clothing. The slim profile of the X-Stretch Unit-X Sling fits flush against your body, offering the squeeze of a hand grip without awkward bunching.
4. Natural Bulge-Enhancing Effect
In addition to intimate play, this sling doubles as a comfortable bulge booster. Pushing the package forward and down fills out jockstraps, athletic wear, and tight clothing cleanly.
5. Multi-Lube Compatible FLEXtpr Construction
Unlike standard TPR accessories that react poorly with lubricants, the non-toxic FLEXtpr material is completely body-safe and compatible with both water-based formulas and silicone lubricants.
How to Wear and Position the X-Stretch Unit-X Sling
- Lubricate First: Apply a generous layer of System JO H2O Water-Based Lubricant or a hybrid glide like System JO Coconut Hybrid Original 4oz over the inner openings to ensure a smooth, pinch-free fit.
- Thread the Shaft: Insert the penis through the top shaft opening first, sliding the sling down to the base.
- Pull Testicles Through: Gently pull one testicle at a time through the lower ball chamber, ensuring the internal ring sits above the testicles to hold them securely low.
- Adjust Fit: Smooth out the outer edges so the FLEXtpr material lies flat against your pubic region without twisting.
For extra base padding during vacuum cylinder sessions, pair this setup with a soft cushion like the Throttle Stroker. You can also browse complete hardware catalog options directly at L.A. Pump.
Care, Maintenance, and Storage Tips
Proper maintenance ensures your FLEXtpr gear remains supple and durable for years:
- Cleaning: Wash with warm water and mild antibacterial soap immediately after every use.
- Drying: Air-dry completely on a towel before storing.
- Powder Treatment: Lightly dust with pure cornstarch to eliminate surface tackiness and preserve the smooth matte finish.
- Storage: Store your toy separately in a breathable cotton pouch or clean sock away from direct sunlight.
Frequently Asked Questions
Can I use silicone lube with the X-Stretch Unit-X Sling?
