1 / 7Under Armour HeatGear Men’s Mock Long Sleeve Compression Top 1369606
Under Armour HeatGear men’s mock long sleeve top 1369606 is a close-fitting performance base layer. The listing describes sweat-wicking, quick-drying fabric, stretch-mesh ventilation panels and a compression fit, so it is aimed at active use rather than a relaxed everyday cut.
