BRAND STORY & PHILOSOPHY

Founded by Kaiji Iida in 2018, IDEUS began with a simple idea: to help reduce plastic pollution through better reusable products.

Driven by a passion for innovation, IDEUS focuses on advancing vacuum insulation technology, improving materials and refining product structures to deliver reliable performance and better everyday experiences.

Inspired by Japanese design sensibilities, we believe functionality and aesthetics should go hand in hand. From everyday coffee moments to outdoor adventures, IDEUS creates products that bring together thoughtful design, practical performance and a more sustainable approach to living.
