Sizes M-XL are American Apparel brand with white drawstrings.
Sizes XXL-4XL are Port & Co. with black drawstrings.
We chose to use Port & Co. for the larger sizes because of their high quality in a roomier fit. The American Apparel jackets are among the nicest on the market, but they run relatively small, especially in 2XL. We generally suggest you go one size up on American Apparel if you don't like a tighter fit.
