Heavy duty 100% cotton shirt with over 50 feet of
medical grade capillary tubing securely stitched
to the front and back of the garment; a compact
cooling unit with an internal pump: 8 feet of
double insulated water hose with automatic shut
off quick disconnect at the shirt, and one foot
electrical hook up. Total weight on this system
is only three pounds for the 12 quart unit
(middle) and only five pounds for the 24 quart
unit. The 12-volt system pulls only 2.7 amps and
lets you keep your cool when other drivers start
to feel fatigued.
