Product Details

The PerfectFit Fat Boy 4.0 Cock Sleeve Penis Extender is made for a more measured upgrade. It adds 0.5 inch of girth, giving a fuller feel while keeping the size boost approachable and easy to enjoy.

SilaSkin is the hero here. This proprietary latex-free material has a velvety texture with superior flexibility and stretch, giving the sleeve an ultra-real feel that moves with the body instead of fighting it.

The scrotum loop helps keep the sleeve secure during play and adds a gentle tug sensation while stroking or penetrating. Small detail, big payoff.

Because the sheath is shorter and slimmer than bulkier extender styles, it is a strong first step into sheaths or a smart choice when you want “just enough” added girth with maximum comfort.
