Ariat Men’s Workwear is designed for demanding jobs, offering durability, safety, and a true-to-size fit that supports long hours of movement. Ariat uses standard men’s sizing with room through the chest, shoulders, and arms, allowing most customers to confidently choose their regular size. If you plan to layer or prefer a looser fit, sizing up can provide added comfort.

Flame-resistant styles like the FR Scorcese Snap Work Shirt, Flame Resistant Lever Button Up Work Shirt, and Flame Resistant Winch Snap Work Shirt are built with structured yet comfortable fits that meet safety standards while allowing flexibility on the job. These shirts may feel slightly firm at first but break in with wear while maintaining their protective performance.

Choosing the correct size ensures all-day comfort, reliable protection, and long-lasting durability, making Ariat men’s workwear a trusted choice for tough work environments.
