Lightweight, breathable, insulated hoody; Ideal as a standalone piece in fair weather, or as a layering piece in cold conditions. Atom Series: Synthetic insulated mid layers | LT: Lightweight.

This trim hybrid hoody is designed as an active-use insulation layer, providing vital core warmth with liberal mobility and breathability. Lightweight and compressible, the Atom LT Hoody features Coreloft™ insulation in the torso, arms and hood. The side panels and underarms feature feature smooth faced, air permeable fleece stretch for ventilation. A wind and moisture resistant outer shell extends stand-alone usability.

ESSENTIAL PIECE

Fact: Every person at Arc'teryx Head Office owns at least one Atom LT; most of the women have two.

The reason: Coreloft™ insulation inside a light taffeta shell. All the comfort of a sleeping bag, but it feels weightless.

WINDSHELL

The benefit of taffeta fabrics is their light, airy nature with an ability to turn aside wind. The Atom series have a taffeta outer lining that is treated with DWR (durable water resistant) finish to give them a long-lasting ability to shed moisture. DWR protects against light precipitation.

NO SWEAT

Mid layers that can function as outer layers have varied degrees of weather shedding capability; they also have varied degrees of moisture management. In addition to being made of breathable Coreloft™ insulation, the Atom LT has smooth faced, air permeable fleece stretch side panels to help regulate temperature during exertion.

PACK LIGHT

Highly compressible, Atom pieces pack down into a tiny parcel of stored warmth. Store the jacket inside its own pocket, or tuck it into a sleeve or inside the hood if you are not restricted by space. A quick shake restores the original loft, time and again.
