The Brest Window umbrella has a mechanism that opens and closes it automatically. The umbrella, made from recycled rPET material, has a reflective band which ensures that you are visible in the dark. 2,6 bottles (0,5 litres) has been used to make one umbrella. Size 21". One of the sectors on the umbrella is see-through, which makes it easier for you to see the road, even in windy and rainy weather. About the material: rPET is gathered from single use plastic, such as PET bottles. The plastic is sorted, cleaned and grined into small grains. The grains are then manufactured into different materials that are used to create new products. This way the plastic that was planneD to be used only once, is recycled and taken into use again.
