RefrigiWearMen’s Iron-Tuff Ice Parka Jacket, -50°F Comfort Rating

Q: I'm 5.95ft tall, waist 37.5 inches, chest 44.3 inches, weight 190lb. what size i should order? large or x-large?

Get absolutely the biggest available. They run undersize. I am 5'7", 145 lb and got Medium. I wish I had gotten large. With a very heavy sweater, the coat is tight. Otherwise it is outstanding - it is warm, it is tough, it is waterproof. But they do run very small.
