Lovers of the great outdoors may not know his name, but they'll almost certainly know the name of his invention: Gore-Tex.
Gizmodo reports the celebrated inventor, engineer, and chemist Robert W. Gore has died. He was 83.
It's easy to keep rain off your clothes by cutting holes in a garbage bag and wearing it like a vest.
However, it prevents the flow of moisture in both directions. Rain is kept out, but your sweat is kept in, making you soggy and unable to regulate your own temperature.
Gore-Tex has around nine-billion microscopic holes per square inch: large enough for sweat and body heat to escape, but too small for rain to get in.
A boon to hikers, campers, and athletes, it keeps the wearer dry no matter the weather or how strenuous the activity.
