Functionality for Everyday Clothing

SARAGAI IRYO CO., LTD. was founded in 1963 and has specialized in manufacturing, importing/exporting, and selling casual wear, mainly denim, through ODM and OEM. The company’s flagship release is the functional material known as "SHELTECH." What led them to develop this material?
"At first, it all started with the idea: 'Can we make denim using functional materials?' Denim tends to be avoided in hot weather, after all.
"Especially with global warming expected to keep progressing, our development concept for 'SHELTECH' was to see if we could contribute to society, even just a little, through this material."
