If you need more details about the short sleeve shirt. Check out the Northwoods Heather colorway on a long sleeve shirt at Revain. The material is also 60% cotton and 40% polyester, which is correctly stated on the long sleeve. Luckily I like the material and color of the shirt I received better than the color and 100% cotton as advertised. The shade of green is only slightly different (I'll send a photo). To recap:::"Check out the green long sleeve shirt for more specific info and colors, then shop the short sleeve shirt"
