This jacket is great for everyday wear, when temperatures are cool. My favorite work jacket in my lineup. The fit is a little slim fitting. I wear a large or XL t-shirt and the large fits snug. So sizing is little small. If you are in between and want a little extra room for layers, I would size up. If you are wearing just a t-shirt I would stick with shirt size. Great quality and great business that makes this in the USA. Highly recommend this jacket.
