Eastbay EVAPOR Half Sleeve Compression Top - Men's The Eastbay Half-Sleeve Compression Top is made with EVAPORô permanent moisture-management fabric that wicks away sweat from the skin to keep you cool and dry. The chafe-free construction, featuring flatlock seams and a tagless interior, lets you focus on your game and your training. Shoulder seams are rolled to the back so they won't chafe under shoulder pads. Compression fit further decreases friction and chafing and helps support the muscles during vigorous activity.
