I've found that most maternity leggings are either too restrictive around my belly or too soft. Nike's tights are the perfect middle ground — stretchy but supportive, with a superwide waistband that allows you to wear it high to cover your entire belly or folded down to fit comfortably below. Because Nike didn't use any elastics on the tight, it truly feels like it moves and grows with your body instead of holding you in too tightly, like other leggings might. The tight is full-length, so it was a little long on me (I'm 5'2"), but I was able to scrunch the legs at my ankle, which didn't bother me during my workout.
