Arc'teryx Men's Atom LT Hoody
Our Take
Atom Series: Synthetic insulated mid-layers. | LT: Lightweight.
Light, versatile synthetically insulated hoody works as a mid-layer and standalone, the Atom LT from Arc'teryx is a key addition to your kit.
Built to handle a range of conditions and output levels, the latest-generation Atom LT’s Coreloft™ Compact insulation retains its warmth even if wet and has loft retention to withstand years of packing and unpacking. The water-resistant Tyono™ 20 face fabric is breathable and durable, stretch side panels improve fit and freedom, and the insulated StormHood™ adds warmth.

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.
