About Sweater Days

Think of your sweater as a portable personal heater you don't plug in.

68° is the target thermostat setting in campus buildings. That can seem warm or cold, depending on the time of day, sunshine factor, your level of activity. Layering clothing is the recommended way to keep the thermostat steady, while staying comfortable throughout the day.

Sweater Days is an environmentally friendly, economically viable, socially equitable and healthy energy conservation awareness and action campaign. Everyone is invited to keep university energy consumption and costs lower during the winter months.

Sustainability is warm, functional, fun, and in style!

sweat•er [swet-er] noun

A knitted jacket or jersey, in pullover or cardigan style; Outer garment, usually knitted or crocheted, that is worn on the upper part of the body, either pulled over the head or buttoned down the front or back, with or without sleeves. Often made of wool, a renewable resource that protects against the cold even when damp.

Although hand knitting of wool had been practiced for about 2,000 years, it was not until the 15th century that the first knitted shirts or tunics were produced on the English Channel islands of Guernsey and Jersey; hence the English name jersey. The use of the jersey spread throughout Europe, especially among working people. In the 1890s it was adopted by athletes in the United States and called a sweater.
