Warm yourself up in Sigma Pi style with Sweatshirts that allow you to represent your fraternity through images, colors and symbols. There's no need to shop your local sporting goods store -- we have just what you need right here at GreekGear.com . Lounge around your house in the fall and winter with a comfortable lettered sweatshirt. It's the ideal thing to wear if you spend as much time outside as you do inside, even when it's cold outside. The sweatshirts we sell are large and roomy enough to pull over your shirt or tank top. Maybe even another sweater. If you want your fraternity insignia to appear on both the front and back of your sweatshirt, get the World Famous Crest Hooded Sweatshirt. The beautifully intricate Sigma Pi crest stretches across the back in purple while your letters appear at the heart of this heavyweight cotton shirt. Just pull it on, throw your keys into the front pocket, put your hoodie over our head and head out the door. You can come here any time and buy Sigma Pi Sweatshirts, jackets, outerwear and other seasonal items that feature your fraternity letters and images. See our selection of t-shirts as well.
