Hyper Subzero Cooler M
This high-performance soft cooler was created as an item that enhances the performance of the "Subzero Pack" series. The soft cooler is resistant to external shocks and protects bottles and other items with its shell-protected structure. The surface is a metallic silver color that reflects sunlight. Unlike hard coolers, which are difficult to store, this cooler can be folded for compact storage when not in use.
We recommend "Subzero Pack -16°C" (sold separately) as a refrigerant. Of course, ordinary refrigerant can be used, but the combination use with "Subzero Pack -16℃" improves the refrigeration effect and ice cream can be stored for up to 13 hours. *It is necessary to follow the conditions described in the explanation section of the comparison experiment. The photo is for illustrative purposes only.
In a room temperature of approx. 33°C, 5 cups of the same type of ice cream are sandwiched inside a Hyper Subzero Cooler M with two Subzero packs of -16°C (1200g), as shown in the figure below. The lid of the cooler was securely closed and the temperature of the rim of the ice cream cups (the part that tends to melt) was measured.
It is possible to use "double speed sub-zero pack" instead of "sub-zero pack -16℃". In this case, the preservation time of ice cream will be shorter. The experiment was conducted with the cooler sealed. If the cooler is opened and closed repeatedly during use, the shelf life will be shortened. The storage time will be shortened if the cooler is exposed to direct sunlight. In the experiment, vanilla ice cream in paper cups was used. The shelf life will vary depending on the type of ice cream. If the cups are individually different heights and have different levels, some of them may not touch the -16°C sub-zero pack, resulting in individual differences in preservation time. If you place ice cream on this part of the container, the ice cream will not be stored for a long time. Ice cream will not be kept cold even if it is placed in this part. Ice cream should be placed in the cooler when it is completely frozen.

Zippers allow compact storage after use.
Capacity for 16 350ml cans or 12 500ml PET bottles and sub-zero packs. The photo shows the XL size.
1) Open the zipper and unfold the shell horizontally. 2) Set the floor foam stored inside firmly on the bottom of the cooler. 3) Be sure to use the cooler with refrigerant as well as items to be cooled. 4) The cooler has a holder to hold a 600g size hard type sub-zero pack or a general hard type refrigerant. 5) After use, only the innermost inner cover secured with Velcro can be removed for cleaning. 5) After use, only the inner-most inner cover secured with Velcro can be removed for cleaning.
1) Raise the floor foam, 2) fold the flap (lid) inward, 3) then fold the left and right walls inward, 4) firmly align the front and rear shells, and 5) slowly close the zipper.
The adoption of a metal silver color that reflects sunlight mitigates internal temperature rises.
It has a unique shape that allows for compact storage, yet provides high cold storage capacity.
