The Durex Invisible Ultra Thin Condom would not have the word invisible added to its name if it was not appropriate. Because it is manufactured to be as ultra thin as can be, it is said to work invisibly. Being the thinnest condom from Durex, it maximizes sensitivity while keeping the protection to the max. It features a straight shape with a reservoir end. This latex condom from Durex also comes already lubricated. Slip one on and feel like you are not wearing one.
