Not all cops are bad but sometimes "Cops Lie".
Our 100% cotton Gildan zip-ups (3X-Large and 4X-Large are 50/50 cotton and polyester) are super high quality that wick away moisture and double stitched throughout. If you dry the zip-ups after washing, it will shrink slightly as the hoodie is 100% cotton. Although they are "pre-shrunk", they tighten up slightly. Please keep that in mind when purchasing.
Recommended care for washing is after removing from washer, dry for 5 minutes then hang dry.
