I can't decide if these guys are for real or not; it's not clear how the devices lock, or even adjust.
But, I like the idea of a fabric-based CB.
My own device uses polypropylene webbing, plus a DIY hard cup.
The innovation here is the mesh penis tube, which really would let you wear the thing 24/7 - assuming it didn't make mince out of your cock!
However, I'm not convinced that this would stop you getting off by simply massaging your cock through the mesh. This design is probably of more interest to TG/TV types than denialists.
