Perfect for outdoor dining (or inside for that matter), casual, modern, yet organic are Alfresco plates by Kinto Japan.   The Alfresco line is not too heavy to easily carry outside , but not too light to blow away with a natural outdoor breeze.

The material is a combination of bamboo fiber and plastic which gives you a refined matte textured finish.
