A new collaborative collection from ARCH & LINE and Ron Herman Kids is now available at Ron Herman stores nationwide and the online store, starting Friday, June 12.

ARCH & LINE is a brand that expresses the most beautiful curves and straight lines through the "patterns" essential to making clothes, always keeping a sense of "playfulness (ARCH)" within "earnestness (LINE)." This collaboration brings in the essence of Ron Herman Kids to create special items that balance playfulness and refinement.
With summers growing increasingly intense, the collection is designed with children's comfort in mind. The lineup includes a short-sleeve henley neck top, shorts, a sleeveless one-piece, a triangular bandana, and an "ACCHIINA (あっちーな!!)" Tee. The four seersucker styles use SOLOTEX®, a high-performance material with supple stretch and shape-recovery properties that keeps its form well even with active movement. The seersucker fabric's textured surface reduces contact with the skin, helping wearers stay cool and comfortable even on sweaty days.

A standout piece in the collection is the triangular bandana, which features a pocket for a reusable ice pack. Worn around the neck, head, or wrist, it helps regulate children's body temperature while adding a stylish accent. A special "&RH" embroidery — unique to this collaboration — is also one of its highlights. The three apparel styles come in navy with a fine check pattern that gives a clean, refreshing impression, making them easy to wear regardless of gender. They also work well for summer occasions.

The "ACCHIINA (あっちーな!!)" Tee features vivid prints that immediately catch the eye. It is an homage to the "BACCAYARO (バッカヤロー!!)" Tee from a past collection, channeling the anxiety over increasingly harsh summer heat and children's well-being into a humorous message. The design aims to spark conversations among those who spot it and to serve as a reminder to pay attention to climate change and the SDGs.
