I am 5'11 175 and wear a Large in Montbell Down Jackets. I am thinking of purchasing a Montbell Tachyron Anorak and am just wondering if this should be sized to go under my down jackets, or over? If over, should 1 size up (XL) be sufficient?
I have searched the forums and found 2 posts regarding this, both stating different view points. They were pretty old posts, so just thought I would see what people think.
