A new Demon Slayer: Kimetsu no Yaiba apparel lineup designed for hot, humid summer nights is on the way from COSPA.
The centerpiece is a jinbei styled after the Demon Slayer Corps, made with COSPA's own fabric for excellent breathability and moisture absorption — an easy-to-wear piece of Japanese-style loungewear equally suited to relaxing at home or a short trip to the store. Alongside it is a four-design dry-material T-shirt series with a smooth, comfortable feel, featuring Tanjiro Kamado, Giyu Tomioka, and Shinobu Kocho. A smartphone case and a mini pouch round out the lineup.
The jinbei and dry T-shirt series get an early release at the COSPA booth during Wonder Festival 2026 [Summer] on July 26 (Sunday), as well as at the COSPA Official Shop and G-Store.com.

Outstanding breathability and moisture absorption in an easy-to-throw-on piece of Japanese-style wear:
- Uses a "shijira weave" fabric with a light, dry texture that resists clinging to skin and breathes well
- Chidori-style stitching where the sleeves meet the shoulders helps ventilation
- One pocket on the top and two on the pants hold a phone or wallet, handy for a quick outing
- Side slits support ease of movement
- An elastic waistband with a drawcord on the pants fits a wide range of body types
- Also recommended as loungewear, or for cooling off in the evening or on a walk
*Shijira weave uses a technique that creates fine, distinctive puckering on the fabric's surface. Because less of the fabric touches the skin, it resists sticking even when you sweat.
