Loopach's "Market Tote" equipped with an inner bag with a cold insulation function. The cold insulation inner bag is detachable and can be separated from the main body. Assuming that it will be used for a long time, the outer bag body can be washed. We have realized a size design and form that is not too bulky with an emphasis on fashion. When shopping on the go is more than expected, you can secure about twice the capacity by separating the cold inner bag and the outer body. The thin and lightweight 75D nylon taffeta fabric developed from scratch for Loopach achieves a firmness despite its thinness. The micro ripstop of the lightweight fabric realized by Japan's technological capabilities has completed an epoch-making bag that is resistant to tearing. The material we used for the memorable first model is biodegradable nylon fiber (Amni Soul Eco®). In order to make the most of the biodegradable material and reduce the environmental impact, no dyeing is performed, and only undyed milky white is developed. Undyed White is a new color expression that we consider stylish. In addition, the name tag with built-in NFC, developed in Japan, becomes a medium for visualizing the action of users refusing plastic bags. The more you hold it over your device and use it, the more you can visualize your contribution to the environment and society on the app.
