Ideal during Alpine adventures as an over layer to preserve body heat during periods of low activity. Atom Series: Synthetic insulated mid layers. LT stands for Lightweight.

Arc’teryx-developed Coreloft™ insulation has a very high warmth-to-weight ratio, meaning it delivers great warmth for very little weight and low profile volume. The resilient structure of the insulation resists compacting, so it can be repeatedly stored and returned to full loft. The outer fabric on the Atom LT Pant is weather-resistant, enabling it to function as an outer layer. Full side zips provide ventilation as desired and open pant legs wide when dressing over equipment.

  • Full side zipper opening adjusts ventilation, opens wide over equipment
