Made from 100% black 'Coated Nylon' with white stripe that extends from the belt loop all the way to the bottom of the UNFINISHED legs. Dual rear pockets with left side button-down flap. Features full belt tunnel loops which will accommodate a 1-1/2 inch or 1-3/4 inch belts. Also includes brass zipper and double snap front closures. Please note: This 'Coated Nylon' does NOT stretch in the rise and waist near as much as the double-knit polyester. We suggest most officials will need to go up one size. Example: If you wear a size 'Large' which covers normal waist sizes 36-38 in the polyester model, in this nylon you might need to move up to size XL.
