Everything counts when you’re in the line of fire, and now a new U.S. Army helmet could give soldiers a slighter advantage by keeping their heads cooler than the enemy, literally.

LiveScience reports that the Army’s Edgewood Chemical Biological Center in Maryland designed the high-tech headgear, which provides chemical and biological protection through a powered air-purifying respirator.

The developers said that unlike traditional respirators, which tend to be heavy and bulky, the new design is much lighter, uses less power and is more comfortable.

From the report: “The helmet consists of a face mask, connected by a hose to a blower unit, and a battery pack that hangs from the soldier’s hip or back.

“The blower sucks air through a filtration system on the side of the mask, creating a flow of air across the face. When the wearer exhales, the valve closes and shunts the filtered air into the mask’s eye cavity, to prevent any outside contaminants from infiltrating the mask if there’s a break in the seal.”

Scientists found that the helmet performed just as effectively as the currently used model during military exercises.
