I love the stretch panels on the sides of the Atom LT. They provide for great range of motion and makes it a lot more breathable than other synthetic insulation piece for high output activities.

Specs Sizing
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.
 
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 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.
