[Zero Transparency/Lines in Summer] tu-hacci Launches 'Puni-Puni Bra' & 'Waterproof Sanitary Pettipants'

tu-hacci, an inner fashion brand operated by WaterAir Inc., released the 'Puni-Puni Bra' featuring a unique 3-layer structure for enhanced adhesion and 'Waterproof Sanitary Pettipants' to protect bottoms from leakage and sweat stains on May 20, 2026.

During the summer months, opportunities to wear tight tops or white pants increase. However, many women face deep concerns such as "the bra cups gapping" or "fear of leakage preventing me from wearing white." tu-hacci proposes a new way of wearing innerwear to resolve these daily issues.

'Puni-Puni Bra': Achieving a secure fit with a 3-layer structure Featuring a 3-layer molded cup with a squishy texture, this bra adheres closely to the bust. Despite being wire-free, it offers strong correction and keeps cleavage. The surface is seamless and comes in skin-blending 'complexion colors,' making it invisible under white clothes.

'Waterproof Sanitary Pettipants': Peace of mind for "those days" Designed with extensive waterproof fabric covering the front, back, and gusset for 360-degree protection. It is perfect for long desk work, traveling, or sleeping, as it handles leakage and sweat stains. The thin, non-bulky material ensures it remains hidden even under light-colored bottoms.
