Custom Stretch Running Waist Bag with Reflective Zipper

Custom Stretch Running Waist Bag & Slim Fitness Belt

This ultra-slim custom stretch running waist bag is engineered for distance runners, gym athletes, marathon participants, and private-label sports programs. Built from high-elasticity, sweat-wicking Nylon Lycra with a water-resistant finish, the structured pouch measures approximately 31.5 × 11.5 cm (12.4 × 4.5 in) and sits completely flat against the body to prevent bouncing during high-speed runs.

The expandable main compartment features a weather-resistant zipper bordered by high-visibility 360° reflective trim for low-light road safety. Internal compartmentalization includes a separate divider and two dedicated card pockets to protect phone screens from scratches, while an integrated cable port supports wired headphones. The wide, extra-stretchy elastic belt with a low-profile quick-release buckle accommodates waists from approximately 60 to 140 cm (23.6–55.1 in).
