Does this jacket have the funny sizing problems that older Millet jackets have had? (Euro sizing is sometimes strange).
I normally tend to ware a medium however should I size up for additional layers?
Yes. For some reason I fit a size small in this and I'm 5'8" 155 lbs and it still looks big and puffy on me. The medium was way too big to be comfortable. Also the tailoring was awkward as the shoulders seem to be extra broad and the armpits and waist are tapered and slim around the torso. So I looked like a big orange triangle. And the color is more of a Hunter's Safey Orange than the yellow gold that is shown on BC pictures.
