JEWLINGE has developed a number of innerwear products for women, but this is its first entry into the men's market. Focusing on discomfort factors such as dampness, tightness, and pressure in the crotch and waist, the company has pursued a structure and materials that reduce stress when worn.

Reviewing clothing that comes in contact with the skin and taking comfort into consideration has become an important perspective in product development, especially in hot and humid environments such as summer in Japan, where the emphasis tends to be on breathability and reduced tightness. This product was developed as an option that responds to such climatic characteristics and changes in the living environment.

Developer's Comment

Nakamura, Patterner, Joulanger

We started developing innerwear that is less constricting and uncomfortable because we heard that people who work under the hot sun and drivers have problems with dampness and rashes. Because underwear is in direct contact with the skin, we are particular about comfort and natural appearance, and have adopted a design that applies the tuck structure of slacks and high-function materials. While incorporating the advantages of loincloths, we focused on a design that would be comfortable for everyday wear.

Background and Application Scenes

The choice of innerwear during the hot and humid season from the rainy season to mid-summer has a significant impact on comfort and hygiene. This product is designed to be worn not only during daytime activities, but also during sleep, relaxation, and various other aspects of daily life.
