Water Air Co., Ltd. (Head office: Hiroshima City, Hiroshima Prefecture; Representative Director: Hideyuki Kuniyasu) operates the innerwear fashion brand "tu-hacci." Starting from 12:00 PM on May 7th (Thursday), tu-hacci will launch the "Pelvic Girdle Contact Cool Type," a new product designed to simultaneously solve "body shape concerns due to light clothing" and "heat and stuffiness" during summer.
■ Resolving the "summer girdle desertion." tu-hacci proposes a new cool-touch corrective style.
As full-fledged summer approaches, interest in "body lines due to light clothing" increases. However, in the market, many women give up wearing girdles due to "heat, stuffiness, and odor." With recent record-breaking heatwaves, innerwear is strongly demanded not only for its corrective power but also for "functionality" and "comfort" to enable long hours of wear.
Responding to these real concerns of women, tu-hacci proposes "inner fashion" that makes every day enjoyable as part of fashion, rather than just "underwear."
To fulfill the desire for "I don't want to compromise on corrective power, but I want to stay cool in summer," tu-hacci has achieved both functionality and comfort. They have developed a new option that allows women to enjoy trendy light clothing styles without worrying about the heat, expressing themselves freely.
24h Comfortable! What are the charms of the "Pelvic Girdle Contact Cool Type"?
■ Instant cool touch, contact-cool material
It adopts a contact-cool material that dissipates heat the moment it touches the skin. Furthermore, its excellent sweat absorption and quick-drying properties prevent stickiness even when sweating, maintaining a constantly smooth skin feel. This completely changes the previous image of corrective innerwear as something "worn while enduring the heat." It allows women to enjoy summer fashion and style enhancement "coolly and comfortably."
■ Deodorizing and antibacterial treatment to block bothersome odor and stuffiness
As a measure against "odor," which is a concern in summer, strong deodorizing and antibacterial treatments have been applied. This specifically suppresses bacterial growth in the delicate crotch lining, maintaining a sense of cleanliness even during long outings. Additionally, the gusseted design allows for "single-piece wear," which is a significant advantage as it prevents bulkiness and allows for cooler wear.
■ Seamless beautiful silhouette focused on "no show-through"
By tailoring the stretchy contact-cool fabric with a "special bonding specification," seams are minimized, designing it to prevent lines from showing even under tight clothes. The moderate compression holds the abdomen and firmly lifts the hips, precisely addressing "pelvic distortion" and "protruding lower abdomen." While providing comfortable wear, it leads to a "-5kg silhouette" just by wearing it.
Four color variations to choose from according to the scene
■ Color Lineup
Black: A classic color that is versatile and helps prevent sheerness.
Ice Grey: A trendy color that gives a cool and clean impression, suitable for summer.
Greige: A versatile color that blends well with the skin and does not show through white bottoms.
Nude Beige: The most opaque and natural color, safe to wear with thin clothes.
Black, Ice Grey, and Greige are available in the same colors as tu-hacci's big hit product, the "Contact Cool Bra Camisole" (Product No.: 90382), allowing for coordinated outfits and body coverage with just these items.
