The Kona is a realistic, 8-inch penis sleeve that’s designed to be a natural solution to ED. Ideal for experienced couples seeking something more on the adventurous side, the Kona is one of our largest sleeves, with an especially substantial girth all the way around.

Like all of our penis sleeves, the Kona is made from certified skin-safe platinum silicone, and it’s available in your choice of firm or soft. Firm is ideal for men who have difficulty maintaining an erection, while soft is suitable for men who can maintain an erection.

This girthy penis sleeve is available in three tones: Caramel, Cocoa, and Vanilla. We recommend checking our sizing guide to ensure the right fit. Be sure to add our Adjustable Inner Rod for only $40—it fills out the air gap for a snug fit that prevents too much bending and flexing during use.

ED happens! Don’t let it stand in the way of a fulfilling sex life. Add the Kona to your cart with full confidence now.
