Enjoy the clean metal finish and open feel of The Siebe Bonnet. This stainless steel chastity cage combines a rounded, open-bar profile with a choice of locking systems and base-ring styles. Choose a classic padlock, a compact integrated lock, a curved base ring or a hinged ring to suit your preferred setup.
Open Bars, Airflow and Comfortable Wear
The gaps between the bars allow air to circulate and make the open design easier to access for cleaning. Its polished metal finish gives The Siebe Bonnet a distinctive look, while the exposed sides preserve its appeal for consensual keyholder play. In our wear testing, the cage was easy to put on and remained comfortable during extended wear without irritation.
Choose Your Lock and Ring Style
-
Padlock: A separate padlock secures the cage to the round base ring. This version allows a small amount of movement between the cage and ring.
-
Integrated Lock: A removable lock core fits into the cage connection, keeping the locking system close to the body of the cage.
-
Integrated Lock + Curved Ring: Combines the integrated locking system with a shaped base ring for a different contact profile.
-
Integrated Lock + Hinged Ring: The base ring opens at its hinge, making it easier to put on and remove without passing through a closed ring.
