Engineered for optimal moisture management, lightly insulated zip aids temperature regulation during active phases, then broadly disperses moisture to evaporate quickly during rest periods to keep you nice. The Arc'teryx Phase AR Zip Neck Long Sleeve for Girl also uses encapsulated silver-ions that provide durable and long-lasting odor control.
