Incredibly soft brushed Pima Cotton. We’ve paid close attention to details and fit, such as angled shoulder seams for a cleaner shoulder line and a spot-on fit that’s not too slim and not too wide. Plus we added a criss-cross center front neck, double seam hood, and a kangaroo pocket with bar-tacking details for extra strength at pocket openings. So really the only thing missing here is the drawstring, but it gives Alvin a much cleaner look (trust us, you won’t miss it).
