The sizing on this jacket does not allow for wearing a layer underneath, unless you are at the lower end of the size range, and the the items you want to layer under it are thin.
The raintech jacket has only a one-way zipper, so you cannot sit without pulling and bunching up the jacket,
completely unzipping it, and closing with the velcro only. That is unacceptable as a design flaw and unacceptable as a cost-cutting measure.
The color, on the compass blue, is closer to a light teal than any shade of medium blue.
