Arc'teryx Women's Atom Hoody
If you have one, you know:
This is one of Arc'teryx's most trusted, best-loved hoodies. Delivering proven, versatile performance as a mid layer or standalone, the Atom LT provides effective warmth for low-output and start-stop activities.
Steeped in the alpine, this versatile hoody has warmed climbers, hikers, backcountry skiers, and downtown commuters. Worn as a mid layer or standalone, it performs across a range of conditions and output levels. Coreloft™ Compact insulation retains warmth even if wet and has loft retention that withstands years of packing and unpacking. The water-resistant Tyono™ 20 face fabric is soft, breathable, and durable, stretch side panels improve ventilation 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.
