The exterior is made of polyester jacquard fabric treated with a protective finish (resistant to water, oil, and stains), lined with breathable mesh, and padded with an EPE foam interlayer. The adjustable webbing shoulder straps include foam padding and feature zinc-alloy spring-loaded safety clips. A zippered side pocket is lined with waterproof fabric. The main opening is secured by a drawstring made of reflective polyester cord. Construction utilizes double-needle flat stitching, with bar-tack reinforcement at high-stress points.
