LOGOS Ultra-Fast Freezing Subzero Pack Series – "Super Speed Freezing Type" Now Available

A new "Super Speed Freezing Type" has joined LOGOS' powerful coolant gel pack line, the "Subzero Pack Series."
This new model freezes in about 1/3 the time compared to conventional models (GT-16℃), taking approximately 12 to 18 hours in a standard household freezer (*1). Just place it in the freezer the night before, and it's ready to use the next day.

When used as a pair, it maintains the same cooling and cold retention power as previous models and delivers approximately 8 times the cooling performance of standard gel packs.
With the fastest freezing speed in the series and high cooling capacity, it’s highly versatile and ideal for outdoor use.

Additionally, it contains plant-based natural materials, making it safe for use.

*The cooling speed being approx. 8 times faster is based on comparison with general-purpose ice packs (at -0°C).
*The freezing speed being approx. 3 times faster is based on comparison with the Subzero Pack GT-16℃.
*Viscosity may vary due to material properties, but this does not affect performance.
