User Review: Arc'teryx Men's Easyrider Jacket
I used this jacket in both Iraq and Afghanistan during the winter season. If you're moving and shaking, yeah, plenty here to keep you warm. HOWEVER, if you just sitting still, this jacket leaves much to be desired in the warmth department.
Another plus was the ability to shed weather right off your back. Rain and sleet were no match for this jacket...it did keep me dry. Highly recommended as part of a layer system.
