Why You'll Love It

The Fat Boy 4.0 Thin focuses on comfortable, understated enhancement rather than maximum size. The stretchy SilaSkin construction provides a soft, realistic feel, while the integrated scrotum loop helps keep the sleeve in position during use.

Who It's Best For

Anyone looking for a modest, easy-to-wear enhancement sleeve rather than a dramatic increase in size. The 0.5-inch girth boost is designed to provide additional sensation while keeping the overall change relatively subtle.

How to Use & Care

Apply a generous amount of water-based lubricant to the penis and inside of the sleeve before fitting.

Gently stretch the sleeve and slide it over the shaft, positioning the integrated scrotum loop comfortably around the base. Make sure the sleeve feels secure but is not excessively tight.

Start slowly when trying the sleeve for the first time and allow your body to adjust to the added girth. Stop using it if you experience pain, numbness, discolouration or excessive pressure.

After use, wash thoroughly with warm water and mild soap. Rinse well and allow the sleeve to dry completely before storing.

Use only water-based lubricants with the SilaSkin material. Store in a cool, dry place away from direct sunlight and heat.

A soft, stretchy cock sleeve designed to add a subtle 0.5-inch increase in girth without dramatically changing overall size.

The Perfect Fit Fat Boy 4.0 Thin is designed for men who want a modest enhancement that's easy to wear and comfortable for both partners. Its soft, flexible SilaSkin material stretches to accommodate different sizes while providing a realistic, skin-like feel.

The integrated scrotum loop helps hold the sleeve securely in place during movement and provides additional sensation around the base. At approximately 4 inches (10.2 cm) long, the sleeve adds around 0.5 inches (1.27 cm) of girth.

The open-ended design keeps the head exposed, while the lightweight construction makes the sleeve easy to put on and remove.
