Collaborative KANNAIGI by Healthknit Terry Set (Unisex)

2026 Spring & Summer Item
A popular kannai-gi set from SAUVEIR that sells out every season
Now arriving with new colors
●Reproduced under the supervision of Healthknit, an underwear brand loved since the early 20th century
●A set inspired by kannai-gi (indoor wear) commonly seen at capsule hotels and public bathhouses, embroidered with SAUVENIR's signature "All Night Sauna" logo
●Sewn using a special "4-needle flat seamer" machine for a soft, natural feel
●Made from loopback (French terry) fabric, it won't feel sticky after the sauna — a welcome point
●The texture is pleasant, so it's also recommended as loungewear
●The design features a henley neck instead of a crew neck, showing attention to detail
●The hook at the waist can hold a sauna key, and the chest pocket stores small items like a coin case
●The pants have a drawcord at the waist for adjustability
Recommended styling
The brand's classic popular model, the SAUVENIR kannai-gi, is back this year.
Recommended not only for sauna-goers but also for concerts, festivals, and time at home. The pieces are easy to use separately rather than as a full set.
The relaxed fit makes this set suitable for both men and women.
