Product Details

The Fat Boy Penis Sleeve Original Ultra Fat Sheath 5.5 Inch Clear is the shorter Ultra Fat option when you want maximum girth without the longer 7 inch fit. It adds 1 inch of girth, giving a bigger, fuller feel while staying easier to manage.

The soft SilaSkin material is the heart of the Fat Boy range. It is stretchy, silky, and flexible, giving the sheath a softer feel than rigid extenders while still adding serious thickness.

The closed tip helps the sheath stay in place, while the thick base loop wraps around the scrotum for added security. Inside, the nubs and ribs add extra sensation for the wearer, so it does more than simply add size.

Best for adding bold girth, internal texture, and a secure fit in a shorter sheath length. Not ideal if you want a thin sleeve, vibration, or latex compatibility, because this sheath is made for water-based lube and should be stored separately from latex products.
