Ariat Men's Rebar M4 DuraStretch Made Tough Straight Leg Pant

What is "ToughMax DuraStretch" fabric?

It is a proprietary blend (cotton, polyester, and spandex) that is engineered to be 2x more durable than standard cotton of the same weight, while still providing the stretch you need to bend, squat, and climb comfortably all day.

How does the "M4" fit differ from the "M5" model?

he M4 is a relaxed fit, meaning it provides more room through the seat, thigh, and waist compared to the more tailored, streamlined M5. If you prefer a looser feel that allows for more layering or extra freedom of movement, the M4 is the better choice.
