Perfect Fit Fat Boy Original Ultra Fat Clear is a premium silicone sheath designed to add substantial girth while delivering stimulation to both partners. The Ultra Fat model adds a full inch of girth, making it the most dramatic option in the Fat Boy line. Its soft, stretchy SilaSkin material combines comfort with intensity, and the closed-tip design ensures it stays securely in place during use.

What Is Perfect Fit Fat Boy Original Ultra Fat Clear?

The Fat Boy Ultra Fat is a stretchy sheath that slides over the penis to increase girth and sensation. Available in two sizes—5.5 inches for medium and 7 inches for large—it delivers consistent, reliable performance. The clear design lets you see exactly what's happening, adding a visual element many couples appreciate.

This sheath functions as both an enhancer and a stroker. For the wearer, interior nubs and ribs create stimulation whether solo or partnered. The thick base loop wraps around the scrotum, delivering a pleasurable tug during penetration or stroking. See the full range in our water based lubes collection for compatibility with this product.

Why This Stands Out

• Adds one full inch of girth for noticeable sensation
• Soft SilaSkin material feels natural and stretches comfortably
• Interior ribbed design stimulates both partners simultaneously
• Secure base loop prevents slipping during use
• Clear material provides visual feedback during partnered play

The Ultra Fat model represents the most dramatic girth increase in the Fat Boy lineup. It's genuinely stretchy—not rigid or restrictive—which means comfort doesn't get sacrificed for intensity. Browse more items in silicone based lubes to optimize your experience with this product.

Material Quality and Body Safety

Made from premium TPR silicone called SilaSkin, this sheath is body-safe and hypoallergenic. The material is non-porous and won't harbor bacteria. It's safe with water-based lubricant only—never use silicone-based products, as they can degrade the material. Store separately from latex items.

How to Use It Best

Getting Started

• Apply water-based lubricant to the inside of the sheath
• Gently roll the sheath onto the erect penis
• Ensure the base loop sits comfortably around the scrotum
• Add lubricant to the outside if needed for smoother penetration
• Remove carefully after use and clean immediately

Enhanced Use and Combinations

The Ultra Fat works beautifully with hand stroking, partnered penetration, or as a manual stroker on its own. Some users apply extra lubricant to the inside ridges for intensified stroking sensations. Experiment with different hand speeds to find what resonates with your body.

Care and Storage

Wash thoroughly with mild soap and warm water immediately after use. Pat dry completely before storing in a cool, dry place away from direct sunlight. Keep separate from latex products and oil-based lubricants. Proper care extends the lifespan significantly.

Feel and Sensations – Honest Expectations

The Ultra Fat delivers noticeable girth increase without feeling restrictive. The interior ribs create pleasant stimulation for the wearer, while the added thickness intensifies sensation for the receiving partner. The closed tip design sits snugly, creating a genuine feel that many find more satisfying than alternatives.

You'll notice the difference immediately upon insertion. The stretch is real but manageable, and the material warms quickly to body temperature. The base loop provides a constant, subtle tug that enhances arousal for many users. Sensation intensity increases with movement and friction.

Why This Product Matters

For many couples, adding girth transforms the entire experience. The receiving partner often reports stronger orgasms from the increased stimulation, while the wearer benefits from the stroker action and the psychological satisfaction of enhanced performance. Solo users appreciate the sheath as both an enhancer and a stroker in one product. The confidence boost from knowing you're delivering more intense sensation matters. Beyond physical pleasure, the Ultra Fat allows partners to explore new dimensions of intimacy together, building connection through shared exploration. It's not just about sensation—it's about mutual satisfaction and the willingness to enhance your intimate life together.

Our In-House Tester Review

I tested the Ultra Fat over several weeks with both solo and partnered use. The material felt premium from the moment I opened the packaging—soft, stretchy, and genuinely sensuous. Rolling it on was straightforward; the stretchy design accommodates different sizes without feeling tight or uncomfortable. The clear construction lets you actually see what's happening, which adds a visual element I didn't expect to appreciate as much as I did.

During solo use, the interior ribs delivered consistent stimulation, and I found myself reaching for this over other strokers regularly. With a partner, the feedback was immediate and enthusiastic. The added girth was noticeable without being extreme, and the base loop delivered that subtle tug that intensified the entire experience. Cleanup was simple—mild soap, warm water, and it was ready to store. After several weeks of regular use, the material maintains its integrity perfectly. Individual results may vary based on anatomy, sensitivity, and usage.

How It Compares to Similar Products

The Ultra Fat stands out because it serves multiple purposes simultaneously—girth enhancement, stroker, and partnered stimulation tool. Cock rings offer subtlety; this delivers drama. Textured strokers focus on hand sensation; this works partnered or solo. It's genuinely versatile.
