Yup, it's a silicone band. I bought it off of Amazon for $20 a little more than a year ago after my real wedding band stopped fitting. When I wore my gold band, I would always take it off at night and would often forget to put it back on in the morning. With the silicone one, I barely notice that I'm wearing it. As long as you don't mind people occasionally asking you what it means, I'd recommend it. Just prepare for people to ask if it means that you're a widow/widower.
