Does what it says
bought this for endurance racing. boot-cut legs make it easy to get shoes on and off between stints. took a wash or two before the smell of new nomex faded. happy with the purchase.

Passed tech no problem
wore this through my first full autocross season. stitching held up fine through a full season of getting in and out of the car. recommend for anyone stepping up from rental gear.
