Beyond this question
Where the winner shows up elsewhere.
context & history
A sports bra does one thing. It holds you still while you move. Everything else follows from that. Some women need more support than others. Some care about feel. Some care about the straps staying put. Some just want to forget they are wearing it. You have to know what matters to you.
The best ones separate on two counts. First, the band stays level and does not ride up. Second, the cups do not shift side to side. Panache, Freya, and Elomi build for larger cup sizes and hold firm. Knix and Shefit focus on adjustability. Nike and Lululemon use thinner fabrics that feel like a second skin. Start there and find what your body tells you.
