Thermos Corporation (Head Office: Minato-ku, Tokyo; President: Yuji Kataoka), a global vacuum flask company that proposes comfortable and environmentally friendly lifestyles for people and society, will launch its new "Cooler Backpack (RFP-016/025)" on Saturday, February 21, 2026. This product is a cooler backpack that frees up both hands and comfortably carries heavy loads while offering cooling functionality. It comes in two sizes, 16L and 25L, and two colors, All Black and Dark Gray, making it easy to match with any fashion and suitable for a wide range of occasions from daily use to outdoor activities. The 16L model uses Thermos's proprietary 3-layer insulation structure "ISOTEC," while the 25L model features Thermos's proprietary 5-layer insulation structure "ISOTEC2." Its high cooling power provides peace of mind for bulk shopping on weekends and during outdoor scenes. The interior is easy to wipe clean and hygienic. Additionally, with a bottom plate, contents remain stable inside. The mesh cushion on the back combines a comfortable fit with breathability, ensuring comfort and preventing stuffiness even on hot days. ◆ Development Background Amidst a heightened interest in "cooling" due to recent intense summers, the need for bags with cooling functions has also expanded with the diversification of lifestyles. This time, with the aim of further expanding usage scenarios and making daily shopping comfortable even in extreme heat, we proceeded with designing a product that "anyone can use regardless of the scene." Furthermore, a survey of our soft cooler users revealed requests such as "we want something that frees up both hands and is easy to use when with children or a stroller." To meet these needs, we embarked on developing a "cooler backpack." Its design differs from conventional "cooler bags," characterized by a design that blends more seamlessly into daily life.
