Our Prices: Ollie only uses the Gildan brand. All shirts are Gildan model 5000 unless we are specifically requested by a customer for a different model. The Gildan 5000 model uses cotton grown in the United States and eco-friendly dye for coloring. All shirts with the exception of high visibility variants are 100% 5.3oz cotton. These shirts are thick and well made, not the thin almost "see through" type that most outlets offer for half the cost of our store.
