At Apex Enterprises we use Bella+Canvas shirts. Depending on the color of the shirt we either use 3001C or 3001CVS. We have not seen a difference in the way the tees wear, just the different hues used with each cotton polyester combination.
Bella+Canvas was started in 1992 by two friends, BELLA+CANVAS co-founders Danny and Marco. The two best friends started a screen printing company right after high school. It did not take long to realize that great fitting and feeling off-the-shelf garments did not exist. They decided right then there to make retail quality apparel for the printwear market and have been changing the industry ever since!
