Approximately 700 bags/person (shopping 3 times a week x 52 weeks) – Contribution to reducing food waste: Prevents deterioration of frozen foods and prepared foods when taken home ・Lifeline in times of disaster: Temporary cooling during power outages and temperature control of room temperature medicines ・Sustainable material: Tyvek is a single material, high-density PE, and can be recycled as nonwoven fabric “365FReeezDesign” development story 1. What made us start “Cooler bags are ‘not cold, heavy, don’t hold anything, leak water and juices, and are unfashionable.’ We had the same complaints.” We felt the same way. That’s why we decided to make a bag that would change ‘everything. 2. Trial and error Materials that cool are heavy. Light materials are easy to tear. If you improve the design, the price will go up. Amidst all of this, we came across Tyvek material from DuPont(TM) of the United States. 3. Completion When the
ultra-high-spec material DuPont Tyvek is applied to the bag, it is water-resistant (water-repellent and stain-resistant), unbreakable (tear strength ◎), overwhelmingly light, incredible cold retention, large capacity, and a design that looks great on anyone who carries it. After repeated testing of cooling power, load capacity and materials, we have finally completed a “lifetime” cooler bag that is “the best companion you’ll want to use 365 days a year”. A cooler bag that has been made with a generous amount of time and skill.
