I have been looking for a "perfect fit" polo for a long time. Polo shopping in the past has been frustrating to say the least. There is always something that is not right. I have to say this shirt excels in every area. The collar is sturdy. It is truly a slim fit. It is long enough even for someone slightly longer in the torso. The sleeves are close fitting. I do prefer an open sleeve as opposed to the ribbed sleeve look but I would imagine the ribbed sleeve will be more durable.I agree the shirt runs just a bit small over all and shrinks just a tiny bit after one trip through the washer and dryer. Personally I seem be in between a medium and a large for all other shirts so, for me, a large ended up being the perfect fit. If you are in between sizes then order up.
