Dickies is the standard reference point for hardwearing workwear: the Redhawk Pro trouser for a heavier work day, the Everyday Flex range for a lighter, more mobile cut, and the Holster utility trouser with its built-in tool pockets. The Portland shirt covers the top half in a few colourways.
Stock runs deeper in some sizes and colours than others across this range, so if you need a specific size for site the same day, check the listing before ordering rather than assuming it's in.
