Most shirts are Gildan Softstyle Brand. Some are Anvil or Next Level. We only use the Heathered Colors and they are all 65% polyester/35% cotton. Please allow 7-14 business days for you to receive your order of bleached blanks. I only have listed the sizes and colors I have on hand. These shirts are getting very hard to find so if it says sold out, I can’t get it right now.
