Introducing this year's Top Pick for Warmth! The Arc'teryx Atom AR Hoody really stands out among all the jackets tested because of its fantastic features and beefy insulation. Most jackets in this review had 60 g/m2 of insulation, but this one hosts twice as much. Additionally, the thicker shell material is heavy duty, protecting you from the wind and rain. It also features an adjustable hood and well-designed stretchy cuff gaskets that wrap around your wrists to conserve heat. With one pull, you have a hood that encompasses the perimeter of your face.
Although the AR provides extra warmth, it's bulkier than many of its competitors. When our testers tried to wear it under tighter, less bulky shells, they still found themselves almost immobilized by the beefy puff of the Atom AR's arms. That said, we would still recommend bringing this jacket on longer colder missions, but you might want to make sure it's on top of your shell, or buy a shell that is larger. Other than that, this was the warmest jacket tested, earning its place as the Top Pick for Warmth. Also check out the Atom AR's little cousin, the Arc'teryx Atom LT - Women's - a time-tested and more breathable option.
