Silicone C-Ring

This one is all about give. The Go Pro is a soft, stretchy silicone ring that slips on without a fight and then settles into a broad, even squeeze rather than a pinch, so it stays comfortable enough to leave on through a whole session.

The flat band is the trick: instead of a thin cord that rolls and shifts, it lies against the skin for a no-slip hold at the base. That steady pressure keeps things firmer for longer and stretches out the finish.

It is molded from body-safe, hypoallergenic silicone with a satin-smooth finish, and there is nothing to charge and nothing to set. The inner diameter is 1.5 inches and the band is 0.5 inches wide; wash it with soap and water, let it air dry, and pair it with a water-based lubricant to keep the silicone happy.
