The Brown / Green Scrub Top is 100% Cotton.

The Halloween Scrub Top is 55% Cotton and 45% Polyester.

The Floral / Breast Cancer Awareness Scrub Top is 65% Polyester and 35% Cotton.

They are all very nice tops with pockets on the front. They still have alot of life in them and will make nice additions to your work wardrobe. The Floral / Breast Cancer Awareness Scrub Top has a couple tiny stains. I did try to clean the one on the back and it wouldn't come out. In the photos, I showed you there location so you could see just how tiny they are. The pattern is quite busy so I don't think they'll be noticeable at all. See photos.
