I bought this jacket last summer and put it away, expecting it to be my go-to winter jacket but since then I have picked up a Black Diamond parka so unfortunately I have no use for itDESCRIPTIONMens moisture resistant warm Polartec® insulation jacket.

A wind and moisture resistant outer shell extends stand-alone usability.Essential PieceFact: 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.WindshellThe 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 SweatMid 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 LightHighly 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.Primary UseSki/SnowboardIce ClimbingAlpine ClimbingHikingTrekkingTechnical FeaturesMoisture-resistant outer face fabricBreathableInsulatedLightweightCompressible and packableWind resistantConstructionDWR finish (Durable Water Repellent) helps repel water from fabric surfaceComposite constructionBreathable, stretch side panels for enhanced comfort and mobilityPatterningArticulated elbowsGusseted underarmsHood ConfigurationScubaHood™Insulated hoodHood fits under helmetZippers & Fly ConfigurationFull front zip with wind flapCuff & Sleeves ConfigurationHem ConfigurationLaminated hemDrop back hemAdjustable hem drawcordPocket ConfigurationInternal chest pocketTwo hand pocketsCenterback Length: 74 cm / 29 inWeight: 360 g / 12.7 oz (Size M)Tinthan™ / 100% NylonPolartec® Power Stretch® with Hardface® Technology / 88% Polyester, 12% Elastane, 230 g/m².
