Salalist's first kimono-specific sweat-absorbing innerwear, protecting kimonos from sweat with its expertise in quick-drying and sweat-stain prevention.
【Development Background】
In modern Japan, where increasingly severe summers are becoming a social issue, many people feel that the three layers of juban, nagajuban, and kimono, which are basic for wearing kimonos, along with the obi, can make them "feel hot and stuffy." Additionally, many kimonos cannot be washed at home if stained with sweat, leading to challenges in care methods and frequency. While the kimono market continues to shrink due to lifestyle changes, rental demand for kimonos is increasing in tourist destinations and for events like Coming-of-Age ceremonies and graduation ceremonies. Many people also wear yukatas in summer, showing diverse ways of enjoying Japanese traditional wear according to the season. Furthermore, a strong base of kimono enthusiasts continues to exist, with a growing segment enjoying Japanese traditional wear with a new sensibility, such as arranging recycled kimonos or coordinating them with modern styles. Against this background, a development project for Salalist's kimono-specific innerwear was launched, leveraging the excellent quick-drying and sweat-stain prevention functions of the sweat-countering innerwear "Salalist" to "protect kimonos from sweat stains while enjoying them beautifully and comfortably." In its development, feedback from employees knowledgeable about kimonos was incorporated, resulting in a design that doesn't use ties, making it easy to wear and eliminating the need to worry about tightness. Furthermore, considerations unique to kimono innerwear were added, such as a deep neckline to prevent the innerwear from showing from the chest or back of the collar, with various ingenuities throughout.
【Product Features】
* Adopted an extra-large pad with deodorizing treatment and a waterproof sheet. Prevents sweat transfer to kimonos and yukatas while suppressing unpleasant odors.
* Calculated cutting for neckline, sleeve length, and body length prevents the innerwear from being visible from under the kimono.
* It is a one-piece type that serves the roles of both a hadajuban (upper body innerwear) and a susoyoke (lower body wrap-around skirt type innerwear), covering sweat from the entire body.
* The connection position between the upper and lower body parts has been adjusted to eliminate discomfort caused by the seam being directly under the obi.
* The deep slit part uses a thin and soft tricot material, which provides good glide and does not hinder leg movement.
* Since it can be machine washed after wearing, it reduces the burden of care.
* Uses an all-season compatible material that can be used regardless of the season.
New items added to the "Cotton Blend Mesh Sweat-Absorbing Innerwear"! Features fabric approximately 40% lighter and 45% more breathable than the conventional "Salalist (100% Cotton Series)".
【Development Background】
According to a "Survey on Sweat"*2 conducted by Belle Maison targeting 10,000 men and women aged 25-54 nationwide, 51.5% of those who have concerns about sweat and do not wear innerwear in summer answered that they "want to avoid layering due to heat." On the other hand, 18.7% of those who wear innerwear in summer answered that it is "to prevent sweat stains," revealing a clear need to avoid layering due to heat despite being concerned about sweat stains. Chiho Ui, director of Yasashii Hifuka Akihabara Clinic, who is knowledgeable about sweat and skin problems, commented that "underwear not only provides warmth but also serves as an item to dissipate sweat and release heat in summer. To diffuse sweat, promote evaporation, and consistently maintain a comfortable coolness, it is actually cooler to wear innerwear in summer." Based on this data, innerwear made of a cotton blend mesh material was developed, which is approximately 40% lighter and 45% more breathable than the conventional "Salalist (100% Cotton Series)", reducing the discomfort of layering.
