I ordered two of these tops, to wear them during the cold season when martial arts under the suit and have been fully satisfied with the purchase: The tops are surprisingly well made, various materials are sewn clean. With my 1.90 m size and 85 kilograms weight size L fits wonderfully, the tops are pleasing long and therefore can not slip up. The "compression" is more likely to be understood as "tight fit." The tops fit like a second skin, but not a close. Only the slim-cut neck is initially a little getting used to but no longer falls on later. Overall speaking, the quality of the very tops of the brand Under Armour.
