Eco-Friendly Umbrella Made from Natural and Recycled Materials, Bambrella

Because Co., Ltd. (Headquarters: Setagaya-ku, Tokyo; President & CEO: Kazunori Watanabe) has launched 'bambrella,' a fully blackout umbrella made from bamboo and recycled PET bottles, under its rain gear brand 'U-DAY (U-DAY).' The product returns this year with a refreshed color lineup.

The project began with a mission: to replace the umbrella frame — a component with high environmental impact during both manufacturing and disposal — with an eco-friendly material.

Bamboo is lightweight, strong, flexible, fast-growing, and has low environmental impact even after harvesting. Because focused on bamboo’s exceptional qualities and, in collaboration with woodworking workshops, conducted extensive research to successfully develop it for use as umbrella frames. Bamboo is now reborn as the main ribs, stretchers, handle, handle ring, ferrule, and button. The fabric is made from RE:PET™, a material derived from approximately three recycled PET bottles, and features full blackout treatment. The result is a stylish, high-quality, and eco-conscious fully blackout umbrella.

How To Make Bambrella

Stylish design enhanced with reliable functionality: 100% UV block, full blackout, and all-weather use

PU Coating

Achieves '100% UV cut,' ideal for protection against intense summer sunlight and harmful UV rays. Additionally, it has earned the highest rating of 'UPF50+' under the global UV protection standard UPF, effectively shielding skin from sunburn and other damage.

The inner side of the umbrella features a black polyurethane coating. This absorbs and blocks not only direct sunlight from above but also reflected light from asphalt and ground surfaces — often overlooked. Enjoy outdoor activities in hot seasons with the coolness and peace of mind of walking under a shaded tree.

All Weather

'Bambrella' emphasizes not only environmental friendliness but also high functionality for comfortably navigating today’s extreme climates. The fabric uses a high-performance waterproof material with a special 'polyurethane coating,' achieving a high level of both 【light and heat blocking】 and 【water resistance】.

It smartly handles sudden downpours, such as guerrilla rainstorms, with just one umbrella. You can carry it with confidence every day, even during unpredictable weather seasons.
