Want to use the hotel gym but afraid that the stench of your sweaty fitness wear will infiltrate everything in your suitcase? Look no further than the Champion Vapor, a new series of athletic wear made with Cocona fabric technology (which is a derivative of coconut shells ? yum!) designed to inhibit the growth of bacterial odors while keeping you cool and dry. I tested out the Vapor sports bra ($40, www.championcatalog.com) and flipped for its super-breathable fabric, seamless support, flat-locked construction and moisture-wicking capabilities. Workout after workout and wash after wash, the bra continued to perform like a true champion. Did I smell like roses, post-workout? Not exactly, but that notorious odor that goes hand-in-hand with most of my other workout apparel was nowhere to be found. So stashing a worn sports bra into your baggage presented no problem whatsoever.
