All about this product



The Arc'teryx Men's Atom Vest is a reliable and versatile performer designed to excel across diverse seasons, terrains, and activities. This vest has been elevated by incorporating cutting-edge insulation and material technologies, making it the ultimate companion for outdoor enthusiasts. At the heart of its performance lies the Coreloft Compact synthetic insulation, renowned for retaining warmth even when damp, ensuring you stay comfortable in various conditions. This insulation is remarkably resilient, enduring years of rigorous packing and unpacking without compromising its insulating properties.


The Atom vest features a robust Tyono 20 shell, which provides excellent wind resistance and holds its ground against light weather, allowing you to venture into the outdoors confidently. For enhanced ventilation and freedom of movement, stretch fleece side panels have been strategically integrated. These panels not only aid in regulating your body temperature but also promote flexibility during your active pursuits.
