Hyper Sub-Zero Cooler with Slip Lid

Introducing the compact size from the Hyper Subzero Cooler Series, designed for easy one-action opening and closing without a zipper.

Despite being zipperless, the slip lid structure, where the protrusion of the lid slides into the recess of the body, maintains excellent cold retention.

When using the Subzero Pack GT-16℃ (sold separately), you can keep a cup of ice cream stored for about 5 hours.

It's the perfect size to hold three 350ml cans along with ice packs, making it convenient for transporting lunches and drinks.

The waterproof inner fabric can be removed and washed, ensuring cleanliness during use.

It's also ideal for storing frozen Subzero Packs as replacements.

It is recommended to use it in conjunction with the separately sold dedicated ice pack, "Subzero Pack (R)."

It is also ideal for storing frozen Subzero Packs as replacements during camping trips.

The hard-type M size can hold up to three packs at most.

We recommend the separately sold dedicated ice pack, "Subzero Pack GT -16℃, Hard 600g."

Of course, you can also use regular ice packs or the Rapid Freeze Subzero Pack M (sold separately), but when used in conjunction with the "Subzero Pack -16℃," the cooling effect is enhanced, allowing you to keep ice cream stored for about 5 hours.

In a room with a temperature of approximately 33℃, we set up two cups of compact ice cream of the same type, along with a sub-zero pack GT-16℃ (600g), inside the Hyper Sub-Zero Cooler with Slip Lid.

Without opening the cooler lid, we measured the temperature at the center of the ice cream.

We determined that the temperature at which the ice cream can still be enjoyed while remaining soft is -7℃, and we measured the time it took to reach -7℃.

● The storage time for ice cream may be shorter, but you can use the "Double Speed Freezing Pack" instead of the "Freezing Pack GT-16℃."

● The tests are conducted without opening and closing the cooler lid. Repeatedly opening and closing it during use will shorten the storage time.

● The storage time will be reduced in direct sunlight or in heated locations.

● The tests used vanilla ice cream in paper cups. The storage time may vary depending on the type of ice cream.

● If the shape of the cup prevents the compact freezing pack from making full contact with the lid, the storage time will be shorter.

● The Freezing Pack GT-16℃ has areas without solvent in part of the container. Ice cream placed in these areas will not be kept cold.

● Please place the freezing pack and ice cream in the slip lid while they are completely frozen.

● Pre-cool the inside of the slip lid before use.

We have uniquely developed a slip lid structure that allows you to close the lid with a simple sliding motion.

The concave shape of the main body and the convex shape of the lid fit together securely, achieving high airtightness and preventing cold air from escaping.

By incorporating a button on one side and a magnet on the other, it is now easier to open and close compared to a zipper, enhancing usability.

When sitting side by side, you can easily open the lid from both sides.

It's convenient for activities like watching sports or during a drive.

The inner lining is waterproof and removable.

It can be easily washed, so you can keep it clean and fresh at all times.

The size is perfect for storing a bento box, two compact ice packs, and a 350ml PET bottle.

Alternatively, it can also accommodate three 350ml cans and an M-sized ice pack.

This item is not only ideal as a bento cooler bag but also serves well for keeping drinks cold during club activities or sports, making it a perfect choice for everyday use.
