I was initially surprised that this sweater doesn't seem much heavier in material weight/thickness than a nice cotton pique polo shirt. (The sweater material is cotton, after all; but it has the texture of a quality brushed cotton fabric with a tight, closed weave and is very soft to the touch.) But, after wearing it, I am impressed by how adaptable it will be as a fall and spring sweater. When the temperatures are low I can wear this over a shirt and forget I have it on even as the temperatures rise into the low sixties in the day. It breathes well, doesn't bunch, is amply cut for the size (a little loose and I like a sweater that way), and has a great, supported collar and v-neck that doesn't roll or creep upward while worn. (If you want a tighter fit you might try the smaller of two sizes if you're in between. In other words, this fine sweater seems about a half a size larger than most of my name brand sweaters of this size.) A mild criticism: although I washed this sweater with lightweight clothing and dried it on the delicate setting in a quality dryer, the sweater does not come out looking wrinkle-free by any means. I turn it inside-out and iron it on a low setting to make it look as sharp as it does in the picture. It seems to keep the light pressing fine. The color is also accurate in the picture. It is not a full-on red, but moves toward the rose end of reds a little and it is a heather pattern. The wrist and waist bands are also great. Some all cotton shirts and sweaters with ribbed cuffs or waist can tighten down when machine dried. This one does not, so far; but I'm using the delicate cycle to prevent this as well as to preserve the brushed cotton finish. There's no way to take off a half a star for the finish even when carefully dried or I'd rate this 4.5 stars.
