I bought this jacket to replace a very similar TNF Scot Schmidt Steep Tech jacket that I've owned for probably 16+ years. These jackets are incredibly durable. I am 6'1" and 200 lbs. and an XL gives me plenty of room for a fleece underlayer. The only issue I see with this jacket is the collar (it is 5" tall and covers my mouth unless I pull the jacket down). My old jacket's collar is only about 3" high. I may see if my tailor can shorten the collar in the front but that would require shortening 3 zippers...I'm not sure how easy that would be. FYI: The belt does come off. I just thought of something, maybe if I used the belt I could keep the collar down off my mouth I will have to investigate this (although I don't like the look of the belt).
