“I have three of these Augusta Full Zip outerwear and they are warm and very comfortable to wear playing golf or for casual wear. I am 5'8" with broad shoulders and weigh 133 lbs and the Medium fits very well. With broad shoulders, I am always concerned about being constricted in a swing....and these do not constrict. I was disappointed in the Sable color of this Augusta Full Zip...mostly because I was trying to match a GG Blue bottom of which I could not get my size in the complementary GG Blue top.”
