Goretex Gorewear C5 running, cycling pants size XS

Very lightweight and waterproof. Lori f zippers. I got this from an outlet. It’s has a tag and never worn but there is one stitch line (see photo with my picture) that is only on one side I can’t tell if it’s an intentional design or sewed to fix something. There are no stitches on the inside so I’m assuming it’s intentional.
