My name is Jeffrey. I am a Stanford engineering Ph.D and a private pilot. Two years ago I was offered a very rare opportunity in Duluth, Minnesota; design a new airplane from a clean sheet of paper.
Winter here is very cold with a lot of snow. Often it is -20°F (-29°C) with 20 mile/h (32 km/h) gust and with a windchill that can plummet temps to –44°F below zero range and lower. One very cold day I asked my colleague “When I go out, I have a jacket for my upper body to stay warm, but how about keeping my legs warm too?” His reply? “Walk fast.” I thought to myself, there has got to be a better way. Necessity became the pursuit of my new invention!

I started sketching. After several sketches I cut up a pair of my pajamas. After running out of used pajamas, I made a prototype using wool fabric with the help of a seamstress. I wore the prototype snow pants everyday during my second winter in Duluth. I was warm and my winter weight reduced from 10 lbs the first winter to 3 lbs the second winter. Then people asked me where to buy the snow pants you can easily wear over your pants to stay warm.
