Arc'Teryx Women's Size Chart 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(TM) insulation in the torso, arms and hood. The side panels and underarms feature smooth faced, air permeable fleece stretch for ventilation. A wind and moisture resistant outer shell extends stand-alone usability. This essential piece has all the comfort of a sleeping bag, but it feels weightless. The taffeta outer lining is treated with a DWR (durable water resistant) finish to shed moisture. In light precipitation, the Atom LT can be worn as an outer layer. In addition to its breathable Coreloft(TM) insulation, the Atom LT has smooth faced, air permeable fleece stretch side panels to help regulate temperature during exertion. Highly compressible, it 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.
