Iruka Gear features fun and colorful dolphin and sea creature images designed by artist Ranke de Vries. Sales of Iruka Gear will help fund the education and research efforts of the Dolphin Communication Project - a non-profit research organization. 'Iruka' is the Japanese word for 'dolphin'; the Japanese (Katakana) characters for 'iruka' are featured in the design logo.
