DESCRIPTION
This trim hybrid jacket is designed as an active-use insulation layer, providing vital core warmth with liberal mobility and breathability. Lightweight and compressible, the Atom LT Jacket features Coreloft™ insulation in the torso and arms. The side panels and underarms feature Polartec® Power Stretch® with Hardface® Technology, delivering stretch mobility and breathability. A wind and moisture resistant outer shell extends stand-alone usability.

ESSENTIAL PIECE
Fact: Every person at 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. In light precipitation, the Atom LT can be worn as an outer layer.

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 breathable side panels of Polartec® Power Stretch® with Hardface™ technology 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.

Atom Series

Atom SL ATOM SL Atom LT ATOM LT Atom AR ATOM AR
Atom insulations are arranged by thermal value and usage. Conditions expected and personal preferences are additional elements to consider when making your selection.
Atom SL - Most compact, lightest weight and easy to layer, the SL is an option for cooler summer mornings or high output activities
Atom LT - Most versatile in terms of insulation, weight and application, often used as an outer layer with weather resistant properties
Atom AR - Colder weather outer layer or cold weather midlayer. The AR has high thermal value for slower paced activities or during rest breaks
