Cecile, Inc. (Headquarters: Shinjuku-ku, Tokyo; President: Masakazu Murakami) launched 'Smart Dry® Sheer Cotton' on April 30, responding to customer requests for thinner and cooler 100% cotton summer innerwear. The lineup includes the 'Lightweight Summer 100% Cotton Sleeveless' and 'Lightweight Summer 100% Cotton 3/4-Sleeve.' Designed to feel almost invisible, the items are perfect for comfortable wear during the hot season.
■Development Background
While Cecile’s 100% cotton innerwear enjoys strong support, some customers sought a thinner, lighter feel for the summer months. Given recent extreme heat, 'Smart Dry® Sheer Cotton' was planned as a summer innerwear that remains thin, light, and cool while keeping the gentle touch of 100% cotton.
■Key Features Realizing the 'Thinnest' in Cecile’s 100% Cotton Lineup
Point 1: Extreme thinness and lightness with fine summer cotton yarn.
To achieve summer-ready thinness and lightness, the product uses ultra-fine cotton yarn. It provides a light wearing sensation, making you forget you’re even wearing it.
Point 2: Rigorous quality verification through repeated wear and washing.
Because the fabric is thin and made of ultra-fine thread, we focused on quality confirmation. As cotton tends to shrink when washed, we selected the fabric after repeatedly wearing and washing multiple samples.
Point 3: Careful sewing to cover seam allowances.
Recognizing that many who choose 100% cotton value skin-friendliness, we adopted a careful sewing technique that stitches down the seam allowances on the skin side.
Point 4: Sweat-wicking, quick-drying, and gentle fit.
In addition to sweat-wicking and quick-drying capabilities, the product offers breathability. It fits gently with just the right amount of stretch to avoid restriction.
