Crazy small head hole - Kryptek Hyperion Short Sleeve Crew - Men's

Like the shirt but can hardly fit my head through. And it doesn’t stretch. I’m a medium, have never encountered this issue before. Didn’t think my head was larger than average but maybe. Looks good once I get it on. Might have gotten an anomaly. Quality is good. Sounds like stitching wants to tear as I force it over but doesn’t.
