#3. Smart condom – waterproof carbon fiber ring
While it’s marketed as a smart condom, the name is a bit of a misnomer. It is actually a small ring that fits on the penis around the base of a regular condom. The ring is made of waterproof carbon fiber and can be adjusted to ensure a snug fit. On the company’s pre-order page, i.Con assures buyers that they can pair it with any condom they wish, though they don’t mention whether it can be worn without one, which a lot of people will presumably try.
