Therefore, the listed chest measurements are <strong>flat garment width</strong>, not body circumference. Body Length at Back is measured from the high point of the shoulder to the finished hem at the back.</p> <p><strong>Important:</strong> SanMar's separate Size Chart also displays a 4XL chest range of 58-61 inches, but the BC3911 product measurements and current product listing only provide measurements for XS through 3XL. Do not use the 4XL range as a garment measurement.</p> <p><strong>Colors:</strong> SanMar lists 9 colors: Athletic Heather, Black, Dark Grey Heather, Dark Lavender, Heather Dust, Heather Forest, Mauve, Navy, and White. No color-specific size restriction is indicated on the specification sheet.</p>
