I ordered shirts for my husband (who is both a Mac Ride evangelist and a big Star Wars fan) and both of our kids as a Fathers Day gift - when a women's shirt arrived by accident, Mac Ride immediately sent a replacement and told me to keep the women's version for free. Good thing, since we switch the Mac Ride between both of our bikes - and now we have soft, quality shirts to boot!
My son and I got matching shirts, love them. Great graphic, soft cotton. I would say the sizing is generous. I am typically a medium, went medium, just a little big.
