Totally awesome jacket, definitely worth the money; WILL buy another Doublju jacket! I would definitely recommend using the size chart that they provide, worked perfectly for me. I am athletically built 6'2"/205lbs that normally wears a 44L jacket & 34" pant; the XXL fits perfectly with a little room to spare around the midsection. If you are any larger than that or larger than a 36 pant it "might" be a little snug. Use the chart & good luck; jacket looks awesome. PS, it's not the warmest jacket ever but not horrible.
