“Hasegawa corporation” handles everything from purchasing raw materials for natural fibers, mainly silk, to processing, production, and sales. It is a comprehensive textile manufacturer that supplies high-quality silk yarn to well-known Western brands.

Under the original brand “HASEGAWA”, they have developed a three-dimensional design mask developed with their own silk yarn. Among them, the “Silk Breath Mask” using the finest extra silk yarn is popular.

The product, which features an ultra-thin and smooth fabric, controls the heat and stuffiness inside the mask by adjusting the length of the string with an adjuster to create a breathing path. The cool contact effect of natural silk makes you feel cool and comfortable in the coming season.
