The Arcteryx Atom Jacket Men’s is a lightly insulated synthetic jacket built for active outdoor use, whether worn as a mid-layer in colder conditions or on its own in milder weather. Its streamlined design keeps bulk to a minimum while offering core warmth wherever you roam.
Featuring Coreloft™ 60 insulation for reliable warmth even when damp, the jacket pairs a Tyono™ 20 wind-resistant face fabric with stretch fleece panels under the arms and at the sides to enhance breathability and freedom of movement. The slim fit follows your body’s contours without feeling constrictive, and at just 330 g it stows easily in your pack when you need to shed a layer.
Coreloft™ 60 is a synthetic insulation that mimics down’s warmth-to-weight ratio but continues to insulate when wet, helping you stay warm in changeable conditions. Tyono™ 20 is a lightweight, stretch-woven nylon fabric that offers wind resistance and durability, while the Bluesign® approval ensures all components meet strict environmental and safety standards during manufacturing.
