I have a light blue, very comfortable material. The label says it's 100% polyester, but feels more like cotton. It even creases like cotton. The pockets close with Velcro, as does the glasses holder above the left breast pocket. Both chest pockets have drainage holes that look more like beauty than practicality. The top of the back is a large ventilated panel with mesh underneath that is stitched down the center of the back to prevent the flap from dangling. Overall this seems like a great product for the price.
