Great Quality and Price
These are the perfect weight for cool Arizona nights and make a great layer for colder climates. The fleece lining is very soft and comfortable and the shirt is true to size. Great price for excellent quality.

By far the best 1/4 pull over zip I have ever bought - 5 stars
This is the most comfortable and best looking pullover 1/4 zip I have ever bought. It looks really good on me and it is super soft, but not too soft that it looks cheap. I did not get hot in it and I get hot easy in long sleeves. It breaths well and yet also kept me from a chilly breeze. The collar is one of the best I have ever found for a pull over like this as it does not poke me and it stays upright and looks very sharp. The only thing about it is that I had to put it in my steam dryer and then hang upside down to dry overnight as it had a few wrinkles in it when it came. So it is not 1,000% wrinkle free, but after wearing it half a day it did not wrinkle at all. As long as you keep it on a long wooden hanger I do not think it will wrinkle. If you dont have long wooden hangers thought, since it is a tad heavy, the shoulders I think would get bumps hanging a long time in the closet on a short hanger (like all long sleeve shirts with a little weight like this would). I got this one as it was I thought the most masculine color match. I would love to see this in other colors and keep everything else the same. I love the inner collar pattern design as it gives it a nice look. I am 5'11" and about 230 lbs and it fit me in a XL perfect. I have broad shoulder and bigger chest and a bit of a dad bod, so I wanted something that is not baggy nor snug on my mid area (so I don't look fat). This is the perfect length too, it is long enough it won't come up if I reach up and show my stomach, and long enough to be a tag long in the back, but short enough that it doesn't look too long. All in all, this size and fit was perfect for me. My style is I want to look good but I have to be comfortable and that is not the easiest to do, but this with some nice pants (of any kind) is a really sharp look and comfortable.

Great shirts at a reasonable price.
Great shirts for the price. The fit is true to size, and they have a quality look that rivals shirts 5 times the price. Definitely recommend.
