Seeking an option smaller than the cb6000s

Any suggestions? I’ve been using it intermittently for some time, mostly at home, but now I want a cage that’s more subtle so I can wear it for longer periods when out in public.

If you prefer plastic models, the Holy Trainer Nub is a well-liked choice. Moving to metal opens up countless small device options. For extended wear periods, I find that traditional metal cages are ideal, primarily because they're easier to clean.
