No accessory is too small to make a big difference. Just ask the adidas by Stella McCartney Lanyard, your trusty new workout faithful. The sporty chic accessory keeps your essentials secure and easily accessible. A nifty detachable hook lets you quickly attach and remove your personal belongings, whether you're swiping your gym pass on the way into class or heading to a café post-sweat session. Wear it across the body for added style. (Not that you need any pointers in that department).
