    Just as described
    Size: X-Large, Color: Black
    Pullover is soft and comfortable. Too soon to comment on shrinkage but quality seems to be good. Not heavy duty but good quality.

    FYI
    Size: 3X-Large, Color: Khaki
    Me and my wife liked the look of the sweatshirt. The color is what I expected. Shirt was comfortable. I got the 3X and it fit pretty good. However I was debating if the 2X would have been better, but I have big shoulders and it may have been tight. Length was pretty good, but my thoughts it could have been just a tad longer.

    Perfect Fit the First Time
    Size: XX-Large, Color: Navy Blue
    This is a really, nice, comfy quarter zip that I wore with just a basic white T-shirt. It was a night out with my significant other and she even complimented how classy it looked. The fit is true to size. I would definitely recommend this product and feel that it is worth the price. It is not only comfortable, it can be worn different ways should you decide to wear a dress shirt underneath. I wear a size 2x and have a size 52 chest. It was not tight and it was not baggy. This definitely felt like a quality product.
