The Under Armour Women's ColdGear Base Layer Bottoms are a popular choice for women tennis players who play in colder weather. These bottoms are made with ColdGear fabric, which traps heat and keeps you warm without weighing you down. The material wicks sweat and dries quickly, keeping you dry and comfortable during matches. The four-way stretch construction allows for a full range of motion, while the ergonomic flatlock seams prevent chafing. These base layer bottoms also feature a wide, flat waistband for a secure and flattering fit. With their thermal properties and performance features, these bottoms are ideal for women playing tennis in colder climates.
