Amoenaâ€™s Comfort+ technology features a temperature-equalizing formula integrated directly into an additional layer in the silicone of the breast form. Breast forms with Comfort+ technology are soft, light and dry. The new super-soft outer film is combined with a lightweight soft silicone formula. The middle layer helps to equalize the temperature in the microclimate around the breast form. The Comfort+ layer absorbs excess body heat from the chest wall during a rise in temperature, which reduces overheating and therefore perspiration behind the form. It also warms the body with the stored heat during a drop in temperature. This effect is observed by a color change indicator.
