Arc'teryx Phase AR Baselayer Pants: These lightly insulated bottoms are engineered for optimal moisture management during stop-and-go activities. During active phases moisture is wicked across the entire garment, aiding temperature regulation. Entering a rest phase the broadly dispersed moisture evaporates quickly, speeding dry-time to keep the user warmer and more comfortable. Encapsulated silver-ions provide durable and long-lasting odor control.
