Arc'teryx PRO Atom LT Hoody Gen 2.1 Men's | Lightweight Tactical Insulated Jacket

Built for Layering, Mobility, and Mission-Ready Warmth

The Arc'teryx PRO Atom LT Hoody Gen 2.1 is a lightweight insulated jacket designed for high-output environments where mobility and temperature regulation matter. Built for professional use, it functions as both a standalone outer layer and a highly efficient midlayer under a shell.

If you are searching for a tactical insulated jacket, Arc'teryx LEAF Atom LT hoody, lightweight military midlayer, or breathable cold weather layer, this is one of the most trusted options available.

Lightweight Insulation That Performs Under Pressure

Powered by 2oz CLIMASHIELD Combat Fibrefill insulation, the Atom LT delivers consistent warmth without adding bulk. It retains heat even when damp, making it reliable in unpredictable conditions.

Breathable, Durable Fabric Construction

The combination of TORAY mechanical stretch fabric and LI PENG nylon ripstop provides durability and airflow where you need it. It is tough enough for field use while remaining breathable during movement.

Built for Movement and Layering

The military fit is designed to move with your body and integrate cleanly into layered systems. It stays streamlined under plate carriers or shells without bunching or restricting mobility.

Integrated Hood for On-Demand Protection

The insulated hood adds quick coverage when conditions shift, giving you additional warmth without needing to change layers.

Smart Design Details for Real Use

Features like vertically routed hem drawcords reduce snag hazards, while the No Slip Zip™ keeps the jacket secure during movement.

Functional Storage for Essentials

Zippered hand pockets with media ports and a chest pocket keep critical items secure and accessible without interfering with your kit.

Why We Love the Arc'teryx PRO Atom LT Hoody Gen 2.1:

It is one of the most versatile layers you can own.
