Underwear brand HIPSHOP has announced a major expansion of its ongoing “KAMEN RIDER Series” collaboration, adding Kamen Rider Zetts and Kamen Rider Nox to the lineup. The collection now spans 86 designs, bringing together Riders from across the Showa, Heisei, and Reiwa eras.

About Kamen Rider Zetts

The Kamen Rider franchise — created by Shotaro Ishinomori and first broadcast in 1971 — has captivated audiences of all ages for over five decades. The latest entry, Kamen Rider Zetts, aired from September 2025 to August 2026 across 50 episodes. The series follows Yorozu Baku, a self-described ordinary young man thrust into heroic action, played by Ryutaro Imai. A theatrical crossover film, Kamen Rider Zetts & Super Space Detective Gavan: Infinity W Hero Summer Movie 2026, was released in July 2026 to considerable buzz.

Refined Designs Inspired by the World of Zetts

The new additions feature a more sophisticated aesthetic tailored to the visual identity of Kamen Rider Zetts. Each product comes in character-specific packaging, making the items as collectible as they are wearable — a must-have for dedicated fans.

Kids Sizes Coming Soon

To let fans of every generation wear their favourite Rider, HIPSHOP will also release Kamen Rider Zetts designs in kids’ sizes (110 and 130), though an exact release date has yet to be announced. Adult sizes are available in M, L, and LL.

Materials and Style

The underwear is crafted from a quick-dry, stretch polyester fabric that wicks moisture efficiently and maintains a smooth feel throughout the day. The boxer style is suitable for both men and women.

Where to Buy

The KAMEN RIDER Series collection is available at all HIPSHOP retail locations, the HIPSHOP official online store, ZOZOTOWN, and Rakuten ONLINE STORE. The items make an ideal gift for any Kamen Rider fan.
