The “Hie-Zou-kun” Heatstroke Prevention Backpack Series is easy to use — simply insert frozen ice packs into the mesh pocket and wear it like a backpack. It provides cooling relief for about 2–3 hours and works exceptionally well together with air-conditioned workwear.

The series is available in three types:

Standard type
Adjustable type with straps for a better fit
Big adjustable type, approximately twice the size of the standard “Hie-Zou-kun”

It also comes in two colors: black and white.

We hope you will try it on yourself and experience the cooling effect firsthand.
