OUTDOOR PRODUCTS, born in Los Angeles, USA in 1973, is a brand loved worldwide for its simple, durable, and easy-to-use bag designs. Combining timeless design with high practicality, it serves a wide range of scenes from commuting and school to weekend outings. Now, a retro-cute series has arrived featuring a collaboration between such OUTDOOR PRODUCTS and classic Sanrio characters!


Hello! I’m Sekai, a virtual reporter who wants everyone to experience the charm of character goods, both old and new. This time, I’d like to introduce pen cases and pouches from a collaboration between the sporty-looking “OUTDOOR PRODUCTS” and Sanrio Characters. The illustrations of classic Sanrio characters feel nostalgic, with a retro atmosphere that captures the heart. These are items that combine everyday usability with a retro cuteness that adults can also enjoy.
