Ariat partners with Polartec for next-to-skin comfort in a flame resistant baselayer that looks great all on its own. Polartec Power Dry FR stays dry next-to-skin by drawing 30% more moisture away from the body, and spreading it across the surface for faster evaporation. Ariat Moisture Movement Technology draws moisture out for quick evaporation, keeping you dry and comfortable. Extended inseam construction improves range of motion so cuffs don't ride up and shirt stays tucked in.
