New without box New ultra lightweight silicone formulation makes the weight of the form nearly 40% less than standard silicone forms of the same shapes and size, while maintaining standards for durability. Slightly firmer lightweight silicone in the back layer helps stabilize the form when worn in a bra pocket. Patented Comfort+ temperature-equalizing material integrated into the back layer regulates fluctuations in body heat to help reduce perspiration behind the form.
