The Arcteryx Women's Motus Crew SS. The Motus leverages Phasic™ SL fabric’s bi-component structure to elevate the level of moisture dispersion. The fabric regulates body temperature during active phases, and dries faster during rest phases.
Phasic™ SL—70% polyester, 30% polypropylene, UPF 25, 98 g/m². Reduced yarn size of polypropylene lends soft touch to 100% hydrophobic jersey knit textile with mechanical stretch. Composed of multidimensional polyester yarns that wick moisture laterally to dry quickly. Very light weight with a smooth outer face that slides easily under other layers.
