## Emma's take

An extra inch of fullness, with a tug that follows every stroke.

The Fat Boy Ultra Fat sheath is for anyone chasing extra fullness without changing partners or positions. Perfect Fit's stretchy SilaSkin adds a full inch of girth, and the closed tip plus scrotum loop keep it seated through penetration or stroking, with a tug at the base built in for the wearer. Anyone after real added length, or a fully hollow design, should look elsewhere; this one is girth-focused and needs an existing erection to hold its shape. Warm up with extra lube and let the stretchy fit do the rest.

## Frequently asked questions

## What makes the Fat Boy Ultra Fat sheath different from the original Fat Boy Sport?

It's the same stretchy SilaSkin girth sheath, now updated with vertical storage packaging and refined at the base for an easier, more secure fit. The 1 inch girth boost and scrotum loop carry over unchanged.

## How do I put the sheath on and keep it in place?

Slide the closed tip over the head first, then unroll the SilaSkin down the shaft and loop the base ring around the scrotum. The loop is what keeps it seated through penetration or stroking, and reviewers describe the fit as easy to adjust mid-session.

## How do I clean and store the sheath between uses?

Rinse with mild soap and warm water, then air dry completely before returning it to its case. Keep it away from heat and direct sun so the stretchy material holds its shape.

## What kind of lube works with the SilaSkin material?

Stick to water-based lube. Oil-based and silicone-based formulas can break down SilaSkin over time, so water-based keeps both the sheath and the fit intact.

## Does the sheath require an erection to work?

Yes. This is a supportive sheath, not a hollow strap-on, so it slides on and holds its shape around an existing erection rather than replacing one.
