Doctor East Co., Ltd. (Headquarters: Ginza, Chuo-ku, Tokyo; President and CEO: Yoji Ito) announces the launch of new colors—'Skin Beige' for women and 'White' for men—for its DERIT TECH (hereinafter 'Derit Tech') functional innerwear series: the 'Functional Innerwear Tank Top (Women’s)' and 'Functional Innerwear Crew Neck Short-Sleeve Shirt (Men’s)'. Available from June 17, 2026, on the official website and Amazon, each piece is priced at 7,800 yen (tax included).
The 'Functional Innerwear Tank Top' supports women’s naturally forward-leaning posture due to chest weight, while the 'Functional Innerwear Crew Neck Short-Sleeve Shirt' enhances support for the trapezius muscle, addressing men’s tendency to unconsciously tense their shoulders. Both products also target the shoulder blades for improved alignment.
DERIT TECH applies the innovative 'Low Muscle Pressure Theory,' incorporating subtle fabric textures aligned with key muscle groups. These textures stimulate skin sensory receptors, engaging muscles without strain. Simply by replacing everyday innerwear, users can support pelvic stability and achieve a more balanced posture. With the addition of spring and summer-friendly colors, the product line becomes more suitable for daily wear.
【Product Features】
① Supports the Pelvis via Upper-Body Alignment
The textured fabric activates skin sensory receptors, supporting muscles around the spine and promoting natural pelvic alignment. This helps alleviate discomfort in the neck, back, and waist, encouraging an ideal S-curve posture and enhanced physical performance.
② Posture Support Tailored to Gender-Specific Body Characteristics
For women, the design targets the sternum and latissimus dorsi to correct forward-leaning posture caused by breast weight. Support for the pectoralis major also enhances décolletage, promoting a graceful, feminine silhouette. For men, who often unconsciously tense their shoulders due to higher muscle mass, the product supports the trapezius to encourage muscle relaxation and guide the body toward its natural posture.
③ New Spring/Summer-Friendly Colors for Everyday Wear
The new 'Skin Beige' and 'White' colors are designed to be easily worn under light-colored outerwear. Combined with existing colors, this expanded palette supports versatile use across various daily scenarios, especially for busy men.
