The light weight NBD cooling system is your ticket to eliminating that fatigue feeling.

The system has a small quite inbuilt fan which blows air through tubes that are encased in none toxic iced cartridge.

The iced cartridge is placed in the freezer for a minimum of 2 hours to bring the temperature down below 0 Deg. C.
