Introducing: Make Me Sweat ® Workout Wear! Man made genius with a sense of fashion. Neoprene rubber like material is now being done right. Wrapped in smooth flexible nylon inside and out, reinforced seams for long lasting wear, this beautifully designed bolero provides adequate compression and flexibility for light to heavy workouts. No need for garbage bag looking sauna suits! It normally takes 45 minutes into a workout to begin burning weight reducing calories. This heat inducing jacket creates an immediate sauna sensation helping you to melt away needless water weight with greater intensity while releasing harmful toxins from their body. Simply wearing this vest while washing your car, mowing the lawn or enjoying brisk walks in your neighborhood will make you sweat away extra water weight in those troubling areas you want to trim down the most...your back, shoulders, upper underarm, bra-line and upper abdomen. Most importantly, remember to rehydrate responsibly. NOTE: "Large" size will not fit 'D' cup or higher, be on the look out for XL coming soon! » Machine wash, cold, light tumble or hang to dry
