You might be winning every race in the Rocky Mountains with this Racerback Tank Top. The style works year round as a must have for the summer, layered in the winter or your favourite pyjamas year-round! 65% Polyester, 35% Cotton blend, 6 oz., ring-spun softness, slim fit, ribbed binding around neck and armholes and a racerback style. We would have shown the back in this photoshoot but it's Canada... it was a little cold that day!
