The Coast is a 7.4” long thin penis sleeve designed for those who want less girth and more length. The head of the Coast model is tapered to perfectly complement its cylindrical 5” shaft, making insertion easier. The girth of the inner hole is suited for natural girths of either 4”, and hard or soft erections up to 5.5” long. You can customize the length for a perfect fit with an Adjustable Inner Rod & you can customize the girth with a Girth Enhancer.

The shape, length, and girth of Coast are designed for easy insertion to help give you and your partner the experience you both desire. With an impressive external length and modest external girth, the Coast is for couples looking for an experience that’s above-average.
