The Chill Killer is the perfect product for outdoor activities during the cold. It has been medically tested under the supervision of two doctors and one professor at the University of Stevens Point.
They tested on 15 people: Those wearing no Chill Killer, those with it on, and those with it on and the hand warmers in the pockets.
The participants were exposed to the elements for 23 minutes at 12 degrees Fahrenheit. They tested their dexterity, reaction time, gross motor strength, and comfort levels.
The group that did have on the Chill Killer, with the hand warmers installed, performed the best overall.
