Our Atom LT products have non-locking zippers by design. One purpose of the non-locking zipper is that it is easier to operate with one hand. This design feature also helps to limit the possibility of damage to the zipper and lightweight face fabric directly adjacent to the zipper.
Versatile combination for layering on cold wet days or as an outer layer in cold dry conditions. Tthis warm mid-layer features composite materials that provide balanced warmth and breathability. The arms and torso are fortified with Coreloft™ insulation, and the side panels and underarms incorporate Polartec® Power Stretch® with Hardface® Technology to increase mobility and breathability. A wind and moisture resistant outer shell extends stand-alone usability.
