Gildan G300 Ultra Cotton® T-Shirt – Classic Fit. Custom Ready.
The Gildan G300 (Ultra Cotton® 3000) is your dependable go-to for durability, comfort, and clean, bold prints. Made from 100% preshrunk U.S. cotton, this tee feels soft but holds up strong — perfect for everything from casual wear to promotional projects.
At Assembly Apparel, we use high-quality DTF (Direct-to-Film) transfers on every G300 shirt to give your design a sharp, lasting finish. And after each shirt is pressed, we treat it with Assembly Apparel’s exclusive DeepSet™ Finishing Spray — our in-house formula designed to lock in color, increase softness, and enhance durability. This is a premium touch most print shops don’t offer, giving you a shirt that looks better and lasts longer.
