This crop tank is made of a heavy 2x1 rib with spandex so it has a flattering stretch. This textile features more compression than our regular cotton spandex styles and has been garment dyed and washed, so it is shrink-free, in 3 basic colors for your wardrobe. Compared to our regular 100% cotton 2x1 crop tank, this garment is better for working out and has a sexier, tighter fit.
