Go bigger on sensation with the Perfect Fit Fat Boy™ Ultra Fat Sheath 5.5" Medium, formerly known as the popular Fat Boy Sport™. Designed for those who enjoy a more substantial enhancement, this ultra-soft penis sleeve adds an impressive 1 inch of girth, combining added fullness with stimulating interior textures for solo and partnered pleasure.
Crafted from Perfect Fit's exclusive SilaSkin™ material, the Fat Boy Ultra Fat delivers a silky, stretchy and remarkably lifelike feel. Its soft construction makes it comfortable to put on and remove, while the closed-tip design and thick integrated scrotum loop help keep the sheath positioned during movement. The loop also creates a gentle tugging sensation during stroking or penetration.
For the receiving partner, the Ultra Fat Sheath provides additional girth and fullness. For the wearer, soft interior nubs and ribs create a satisfying stroker-style sensation with every movement. This combination makes the Fat Boy Ultra Fat a versatile accessory for exploring enhanced stimulation during solo play, manual stimulation or partnered intimacy.
Previously sold as the Fat Boy Sport™, this updated Ultra Fat model features new vertical storage packaging while maintaining the signature design that made the original a popular part of Perfect Fit's Fat Boy collection. With its 5.5-inch length, Medium size and clear finish, the Fat Boy Ultra Fat Sheath offers a distinctive option for those seeking more substantial girth enhancement.

Use & Care
- Before use: Inspect the sheath, interior textures and scrotum loop for tears, damage or deterioration. Do not use if damaged.
- Check sizing: Measure the erect penis from base to tip and consult Perfect Fit's sizing recommendations to confirm the 5.5-inch Medium sheath is appropriate for your needs.
- Lubrication: Apply a small amount of personal lubricant confirmed to be compatible with SilaSkin™. Avoid assuming all lubricant formulas are suitable for this proprietary material.
- Putting it on: Gently stretch the sheath over the penis and carefully position the integrated loop around the base of the scrotum as intended. Do not force the sleeve or pull the loop excessively tight.
- Solo stimulation: Explore gentle stroking movements to experience the soft nubs and ribs along the interior.
- Partnered play: Begin slowly and communicate about comfort. The additional girth may require more lubrication, gradual adjustment and careful positioning.
- Manual stimulation: The sheath can also be explored during hand play using comfortable pressure and material-compatible lubricant.
- Anal play: Use sufficient compatible lubricant, proceed gently and never force penetration. Stop immediately if either partner experiences pain or discomfort.
- Circulation safety: Ensure the scrotum loop never causes pain, numbness, swelling, unusual colour changes or restricted circulation. Remove immediately if any of these occur, and never wear the sheath while sleeping.
- Removal: Carefully release the scrotum loop before gently sliding the sheath off.
- Cleaning: Wash thoroughly with mild soap and water before and after use, as recommended by Perfect Fit. Pay special attention to the interior nubs and ribs, closed tip and scrotum loop.
- Drying: Rinse thoroughly and allow the sheath to dry completely before storage.
- Storage: Store in a clean, cool and dry location away from direct sunlight. Keep separated from other soft toy materials unless compatibility is confirmed.
- Protection: This penis sheath is not a contraceptive and should not be relied upon for protection against sexually transmitted infections.
Staff Tip
The Fat Boy Ultra Fat is designed for those who want a more noticeable increase in fullness than a slimmer penis sleeve. If you're familiar with the original Fat Boy Sport™, this is its updated Ultra Fat version with new packaging. Start slowly, use a SilaSkin™-compatible lubricant and allow time to adjust to the added girth. The textured interior offers stimulation for the wearer, while the scrotum loop should feel supportive without creating uncomfortable pressure.
