Shimano's Mini Cooler Bag Pro, which keeps ice for 8 hours even at 40°C, was selected as the top award winner. Experts provide a detailed explanation of features including the vacuum panel in the base.
Shimano's Mini Cooler Bag Pro was selected for the top award. Priced at ¥8,800, it has a vacuum panel in the base and is said to maintain its cooling performance for 8 hours in summer simply by adding bottled-water ice. The lid is designed to store a cold pack, while its shape makes it easy to lay convenience-store meals and food flat.
POINT1 explains that the vacuum panel in the base is the key to its cooling performance and that ice remains even at temperatures of 40°C. An expert says that the base structure, together with the thick polyurethane, enhances cooling performance.
POINT2 highlights the square shape, which allows boxed meals and food to be laid flat and makes the bag suitable for a wide range of uses, including commuting lunches and solo camping. One view is that its minimalist appearance and ease of use are appealing.
POINT3 presents it as an accessible specification, taking into account its reasonable price and brand strength. Its square shape is unusual for a soft cooler box, and its light weight and convenience are emphasised.
