A. heavy. Silicone stealth bra in general weight of about 100g, and some can weigh more than 400g, previously used this kind of material JMS, wear generally feel chest pressure. B. airtight. Silicone invisible bra, for its own material reasons, from 2003 to the present, there is no breakthrough in the design of improvements (such as ventilation holes, etc.), so the permeability is not good.
