Love the brand, the vendor and these racer back tanks!  I have purchased and been wearing a single in black, a 3 pack of burnout tanks and now solid colors.  The solids are thin and comfortable with no need to wear an undershirt unless you like to layer as I do.  The burnout tanks are thinner, but not completely see through, very comfortable and come in vibrant colors!
  These tanks are great, I bought a single and 2 3packs!!
