The Under Armour Women's HeatGear Sonic Shorty Shorts are manufactured with a lightweight, soft, close, and streamlined fit without the squeeze of compression for extra comfort. The shorts are manufactured with HeatGear® Sonic, a fabric that contains Under Armour's signature Moisture Transport System. This ensures that sweat is drawn away from the body and out into the air so that it can evaporate, ensuring that you remain dry and comfortable. The fabric also features a 4-way stretch, enabling you to move freely and without restriction. Anti-microbial technology prevents the growth of odour microbes, keeping you feeling fresher for longer. Flat-lock seams create a smoother fit, preventing the risk of chafing and friction that can occur from seams that stand away from the garment.
