This unique design has a three-dimensional pearl surface on the back of the breast form that allows air to flow freely behind the form. Amoena Energy Breast form reduces perspiration behind the breast form and increases the evaporation rate during exercise or natural temperature changes. Comfort+ is made up of microcapsules that help regulate and balance fluctuations in body temperature. This patent temperature equalizing material actually absorbs, stores, and releases body heat behind the form – resulting in an unmatched level of comfort. All sizes available in symmetrical and non symmetrical shapes.
