I got this jacket a few days ago and I love it! I wear an extra large t-shirt and I got a large jacket. I live in central Alaska, and it gets down to -40 pretty regularly around these parts. Of course this jacket isn't warm enough for that weather alone, but it fits a little loose allowing for the perfect amount of room to wear a sweatshirt underneath. This is good though because when you're in extreme cold like this, layering is the name of the game.
  Now, though it fits loose to allow for a sweatshirt, it doesn't feel baggy when you wear it without a sweatshirt, which is really nice. Somehow Carhartt makes their stuff like that, it has extra room when you need it, but fits well when you don't, It's a miracle.
  When I was shopping for a jacket I was torn between this one and the same one with arctic quilt print, because I was concerned that: (A.) This one would be too cold and (B.) this one would get dirty when working on cars or doing construction, but now I'm not concerned with either of these. The sherpa lining is just as warm as the arctic lining, and it is not as "fuzzy" as I thought it would be, it's also a darker color than what the pictures show, so a little dirt won't show up as much as you'd think. I have yet to wash it and see if it shrinks, but I would think it wouldn't since it's denim-like. I'll just wash it in cold water and dry it at a low temperature just to make sure.
  I have nothing bad to say about this jacket! It is great, and very reasonable price because these carhartts last 10+ years in heavy work conditions! Bottom Line: Buy this jacket!
