The Green Grade is a grading scale from 0–10, based on two vital factors. The influence of our products on your health and the planet. Just as it is vital to know what food to eat to stay healthy, and to understand how it contributes to your health, we believe the same should apply to your clothing. At DesignHeights, every piece of clothing is fashioned with your health in mind first. As a result, most of our products are organic. It is important to state that some of our product do contain recycled polyester. While this has zero negative impact on your health, we believe that this is not what our planet requires from us. As a result, products with rPET often have a grade range of 9-9.5 out of 10.
