SAUVEIRからレトロな風合いが特徴的な館内着セットアップ
Now available with new colors
●Reproduced under the supervision of Healthknit, a beloved early 20th-century underwear brand.
●A set inspired by the kannai-gi (loungewear commonly seen at capsule hotels and large public baths), embroidered with SAUVENIR's signature 「オールナイトサウナ」 logo.
●Using a special sewing machine called a '4-needle flatseamer' to achieve a soft, natural fit.
●Because it's pile material, it doesn't feel sticky even after the sauna — a nice point.
●Also recommended as roomwear thanks to its pleasant touch.
●The design is a henley neck rather than a crew neck, showing attention to detail.
●The hook at the waist can hold a sauna key, and a chest pocket is provided for small items like a coin case.
●The pants' waist has a drawcord for adjustability.
