Comments: Material blocks all wind but does seem breathable. PitZips work well to vent but are difficult to work with one hand. Hood is LARGE and floppy but can be cinched down with the adjustment. Front zipper zips up far enough to protect lower part of face. Medium, my normal size, seemed big on me but allowed for more layers underneath. A small would have been too tight. Welded construction seems well done. Waist draw cord is easy to adjust. Lining on the inside and in pockets seems just warm enough. Not supposed to be an insulated, "warm" jacket and it isn't. Why do companies NOT include PitZips? The material is water proof and blocks all wind but does not breath well. Hood is just the right size if you do not care about a helmet. Medium is just the right size to layer underneath without billowing in front. Drawcords on hood and at waist are easy to adjust. Stitched seams are taped and seem up to the task. Not supposed to be an insulated, "warm" jacket and it isn't.
Winner: Genesis For superior venting options and better breathability. Freedom of movement is also good but overall seems to run large.
