All SUM SHIRTS unisex T-shirts are made with triblend fabric. We want the shirt to feel as good as the design looks, so softness is part of the starting point.

Halloween is fun. Figuring out a costume that’s clever, comfortable, and doesn’t require overnight shipping? Slightly less fun.

Meet SUM SHIRTS, the Michigan business turning Detroit sports, Midwest life, and everyday humor into your next favorite graphic tee.
