I ordered the Anorak in a large, which has been the right size for me in most 1620 items, except the t-shirts, where I ordered a medium. Even if I wanted to only wear a light layer underneath the Anorak, moving around pulls the sleeves far up my forearms in a large size, and the fit across my shoulders was very close. I probably could have made the large work, but I will primarily use the Anorak for shoveling snow and working, so I returned for an XL. I have a pair of double-knee pants in the same material I have used forat has snow removal th been fantastic, and I am sure the Anorak will be a great piece. Unfortunately, being on the West Coast, the shipping, return, and re-shipping takes quite a long time, so I can't say if the XL will work as well as I hope. I've been using the hooded work jacket in NYCO which has been great, but I am excited for the Anorak material for snow and cold. BTW, I am 6'1" 190 with long arms.
