Description

The Sport-Tek ST312 PosiCharge Tough Mesh Pocket Short is a midweight mesh athletic short with side and back pockets built for athletic programs, coaching staff, PE uniforms, recreational leagues, gym programs, and branded merchandise where a durable, colorfast mesh short with multiple pockets needs to carry a company or team logo for active training, competition, and everyday athletic use. At 5.3 oz, the Tough Mesh delivers a heavier, more substantial mesh construction than standard 3.2 to 3.6 oz mesh shorts for enhanced durability during demanding daily use. PosiCharge technology locks color into the fiber, keeping team colors sharp and consistent through repeated washing without fading.

Made from 5.3 oz, 100% polyester flat-back mesh with PosiCharge technology, the heavier flat-back mesh provides a smooth, opaque exterior surface with breathable mesh construction for ventilation during active use. Side pockets provide accessible storage for a phone, keys, or small essentials. The back hip pocket with a dyed-to-match button provides secure rear storage with a coordinated closure. The elastic waistband with a continuous loop drawcord provides an adjustable, secure fit that stays in place during active movement. The 9-inch inseam provides a standard at-the-knee athletic length. Tag-free label eliminates neck irritation.
