Old Navy goes back to school with denim that grooves: Ballerina 24/7 and Karate.

The clothing and accessories retailer promotes the “stretchiest, most comfy jeans ever”, for girls and boys, in a new commercial, also highlighting that all kids & baby are up to 50% off.

The 15-second spot informs viewers that, between July 24 and August 16, kids jeans are from $10, and is introducing Ballerina 24/7 and Karate. The Ballerina 24/7 Pull-On Jeggings for girls, in a butter-soft, super-stretch knit, features elasticized waistband and faux fly for easy pull-on style, interior adjustable waistband which expands for a perfect fit, and decorative scoop faux-pockets in front and functional patch pockets in back. Their price, originally set at $26.99, is now only $19.00.

The Slim Built-In Flex Max Karate jeans for boys, available in four shades, are described as “powerfully stretchy jeans with major comfort chops and kicks”. They feature innovative stretch technology for maximum comfort and movement, interior adjustable waistband, snap-button closure and zip fly, riveted scoop pockets and coin pocket in front, and patch pockets in back, and cost $19.00, reduced from $29.99.

Old Navy states that its denim “is made to keep up with all the high kicks, art projects, recess games & science experiments this school year has in store” and that any jeans you buy until August 23rd are guaranteed to last through the whole school year, which means that “any pair or kids or toddler jeans that rip or split” will be replaced as long as you bring them back to the store with the original receipt.
