The Arcteryx Atom Jacket Unisex is a lightweight performance piece made for movement—whether you’re layering up for alpine hikes or heading into brisk city mornings.

Its sleek, packable design makes it ideal for travel, training, or day-to-day layering. Browse more Arcteryx outerwear here.

Designed with versatility in mind, the Arcteryx Atom Jacket Unisex features stretch-knit side panels, articulated sleeves, and a gender-neutral silhouette that allows natural movement and a close-to-body fit. Whether you’re tackling trail runs, cool-weather climbs, or daily commutes, this sports  jacket adapts. It’s finished with a DWR coating that sheds light rain and snow, making it a dependable mid-layer or standalone piece.

Personally, I’ve worn the Atom LT jacket through light snow and sharp winds—it holds up impressively while feeling super breathable. It pairs easily with the Arcteryx Cerium Down Vest for colder conditions or the Arcteryx Gamma Pant for full-performance gear. If you’re building a go-anywhere layering system, this is a must-have piece that delivers every time.
