Even Florida gets cold days in the winter (50's and 60's) so I bought a pair of these long sleeve golf shirts for those occasions. The shirts aren't heavy enough to be worn alone in Northern or Midwest winters, but that would require a thicker layer over them - but then how many people play golf in cold climates in the winter? I have some landing problems. I usually wear a size XL with shirts, jackets and sweaters, but this XL shirt offers some upper body flattering, which is partially offset by the addition of spandex to the shirt's material. Also, and this is another problem, the sleeves are too long and reach the middle of the palms; and when the cuffs are folded to shorten the sleeves, the cuffs soon open up when I swing the golf club, forcing me to adjust the cuffs before the next shot. I'm hoping that washing the shirt might somehow fix the cuff length issue and I'll update this review after I try. If the shirt shrinks at all when washed, it is definitely too tight on the upper body. Considering that many of the XL shirts I've bought from Revain fit perfectly, I have to give this product 3 stars for now. .
