Arc'teryx Men's Atom Jacket Black

The Arc'teryx Atom Jacket Men’s in Black is a versatile synthetic insulated layer designed for high output activities across changing conditions. Built as a hoodless alternative to the Atom Hoody, it delivers dependable warmth, breathability, and weather resistance in a streamlined format that works equally well as an outer layer or midlayer.

At its core, the jacket uses Coreloft™ synthetic insulation, chosen for its ability to retain warmth even when exposed to moisture. This makes the Atom Jacket a reliable option for activities where changing weather, sweat, and light precipitation are part of the equation. Unlike down, the insulation maintains performance when wet and dries quickly, supporting consistent comfort during movement.

The outer fabric is lightweight, abrasion resistant, and treated with an FC0 DWR finish, a revised update that lowers environmental impact while continuing to shed light rain and snow. This water resistant treatment enhances versatility without compromising breathability, making the jacket suitable for hiking, climbing, ski touring, and everyday wear in cooler temperatures.

An articulated construction supports unrestricted movement through complex patterning and thoughtful seam placement. This allows the jacket to move naturally with the body, reducing bulk and resistance during active use. The fit is clean and functional, designed to layer easily under a shell or worn alone when conditions allow.

Without a hood, the Atom Jacket offers a more streamlined profile that integrates smoothly into layered systems. It provides warmth through the torso while remaining packable and easy to stow when not in use. The minimalist design and neutral Black colorway ensure the jacket transitions effortlessly between outdoor environments and daily use.

Produced in a Fair Trade Certified™ facility, the Atom Jacket reflects Arc'teryx’s commitment to responsible manufacturing and worker well being. This certification supports ethical production practices alongside the brand’s focus on long term durability and performance.

Designed as a true multi use piece, the Atom Jacket Men’s Black is a dependable insulating layer built to perform year round, adapting to both demanding outdoor objectives and everyday wear through thoughtful material selection and functional design.
