Old Navy in Santee occupies a Trolley Square storefront at 9922 Mission Gorge Road, stocking Gap Inc.'s value-tier clothing line for men, women, children, and toddlers. The denim wall — Old Navy's signature merchandising fixture — displays Wow boot-cut, Rockstar skinny, and Athletic taper fits across a 00-through-30 size spectrum, anchoring a family-apparel selection on the same corridor where Al's Sport Shop outfits outdoor and athletic pursuits. Performance fleece, moisture-wicking activewear, and built-in-flex chinos round out the non-denim inventory with stretch-fabric technology across most categories. Children's and toddler sections stock school uniforms, graphic tees, and stretch-knit separates built for youth tumbling and dance rotations — durable pieces parents grab before enrolling at Expressions Dance & Movement Center on Riverview Parkway. Children's activewear incorporates Gap Inc.'s Go-Dry moisture-wicking treatment bonded into polyester-blend knits, using a capillary-fiber construction that moves perspiration from skin to fabric surface for accelerated evaporation across the full toddler-through-youth size range.
