About Thermic: Our history begins with a declaration of love – to the world's most beautiful sport: skiing. Imagine skiing in the mountains on a beautiful blue-sky day. Fresh powder swirls around you as you make turns down an untracked slope with the sun in your face. Everything is perfect, except for one thing: Cold feet and hands that refuse to stay warm, regardless of how much you stretch them or which high-tech materials you are wearing. It is uncomfortable, annoying, painful and it ruins a perfect experience. The founders of Therm-ic must have had very cold feet because back in the 70s, they decided to deal with the problem.
