NELEUSMen's 3 Pack Running Tank Top Dry Fit Y-Back Athletic Workout Tank Tops

Are these like under armour?

I'm 6'3 and semi musclar build I weigh 305 will a 2x work for me?

I ordened your neleus hooded 3pack and they fit quite fine. i’m wondering if these y backs run the same size, or if i should go with medium?

Individual Sale? I want ti able to pick the colors, not a pre-set selection.
