Our Unisex Geek T-Shirts are made of thick, heavy cotton, but are still soft and very comfy. The double stitching on the neckline and sleeves adds more durability. The style is a ‘Regular Fitted’ which means it’s not boxy and it’s not too fitted either. They're extremely comfortable to wear and will last for a long time. They are available in 4 fabulous colors and in sizes S to 3XL.
