Warmth Where You Need It. Bulk Where You Don’t.

The Arc'teryx PRO Atom LT Hoody (GEN 2.1) is a lightweight insulated layer designed for Special Reconnaissance and high-output field use, whether worn on its own or layered beneath a wet-weather shell when conditions deteriorate.

Built with CLIMASHIELD® Combat Fibrefill insulation, the Atom LT provides efficient warmth without the weight and bulk of a traditional insulated jacket. Lightweight ripstop fabrics keep the package mobile and durable, while POLARTEC® Power Stretch® Hardface™ material adds stretch and breathability where freedom of movement matters most. At just 15.7 oz, it's an easy layer to keep in your pack until temperatures or activity levels call for it.

The insulated hood adds coverage when needed, while the vertically routed hem drawcord is enclosed to help reduce snags around equipment and vegetation. A No Slip Zip™ center-front closure prevents the zipper from working itself open at the collar while you're moving.

Storage is built around field use, with a secure left chest zip pocket and two zippered hand pockets. Integrated media ports and cable-management loops allow communications cables to route from the hand pockets through the jacket, keeping wires controlled and out of the way.

Wear it alone in cool, dry conditions or throw a weatherproof shell over it when things get wet. Either way, it's warmth that knows how to work as part of a system.

Why We Love It

The Atom LT hits that sweet spot where you get legitimate insulation without feeling like you're operating in a sleeping bag. It's light, easy to layer, and the cable-routing system is a small detail that makes a big difference when you're running comms. Keep it packed, pull it out when temperatures drop, and layer a shell over it when the weather decides to get worse.
