Bought it for the colour, not to work out in (only because i don't work out----i can imagine it would be great to work out in). I wear it on crazy-hot days for walking my dog and running errands. Great quality and yes the amaranth purple colour is GORGEOUS. Very soft and stretchy also. I am wearing it right now. Love it so much I'm also going to get the same colour in the t-shirt now.
