Patio Umbrella -Bamboo parasol The material of the ribs - also known as spokes - is bamboo. The bamboo used for the original Bali Parasol undergoes thorough quality checks and is eco sourced from Indonesia. One of the factors considered is the age of the bamboo. Young bamboo is often thin, moist, and more susceptible to stains. Our parasols are exclusively made from thick, rigid, and older bamboo. The wood is dried, fumigated, disinfected, and finally lacquered in a special manner. Our parasols always feature twenty bamboo spokes of the highest quality. This ensures that the parasols are strong and stable. Another important aspect for the shape is that the "growth nodes" of the bamboo parasol are evenly distributed across the entire top so that all tension is evenly distributed everywhere.
