Umiko is a protective face mask that uses a sustainable sea-algae-based material. This material fully breaks down in water within 7 days of disposal with no residual impact. This sustainably harvested material is woven into flat sheets and die-stamped to produce a high-volume, low-cost solution for daily mask wearing. The mask is designed to be light and comfortable, offering filtration and breathability similar to N95 masks. Masks can be quickly fitted to a user’s face with minimal effort. Adjustability over the bridge of the nose and face come from the inherent malleability of the material; it is also adjustable around the ears to ensure a tight fit.
