The Cohesion is a very good jacket for protection from the elements in spring, summer, and autumn. My two bones of contention would be the lack of netting in the pit vents and the fact that the pocket in front of the jacket is too small for some portable music devices such as an iPod if it's in a case. It still is much better than similar jackets made by competing makers.
My favorite feature of the jacket is the pocket on the chest; it is perfect for my ipod. I also love the hood.
