The intimate apparel store has an entire line of sports bras, but the “Incredible by Victoria’s Secret Heart-Rate Monitor Compatible Sport Bra” includes sensors and technology from the Finnish fabric maker Clothing+. You still need to clip on your favorite communications module, but the sensors are built into the fabric itself. No belt needed.
