Arc'teryx Atom LT Hoody Synthetic Mid-Layer My New Favorite

If you had to own only one piece of Arc'teryx gear, it would have to be this one. If you had to own only one piece of clothing in the world, it would have to be this one! this jacket is truly the most wonderfully designed piece of fabric I have ever worn. Whether you live above the arctic circle and need something for spring and fall, or live in the american south and need something for chilly winter nights, this is the jacket you need. Comfortable, light, packable, warm when its cold, breathable when its hot, stylish, this jacket does it all.

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 Polartec® Power Stretch® with Hardface® Technology, delivering stretch mobility and breathability. A wind and moisture resistant outer shell extends stand-alone usability.


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.

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.

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.
