The 155 is Koi's new not so basic, basic scrub top. This top is roomy but shapely, it's slightly longer than the Ashley scrub top. It features a cute sweatshirt like neck detail stitching, two patch pockets with whip stitch detail, side slits and a twill tape tab on the left shoulder to hold a clip badge. 55/45 cotton/poly. The approximate length for size M is 28.75".
