I love these suits! Wear them when you work out and you work up extra sweat!! The more you sweat, the more access your body has to lose FAT. They are thin, so DUH you don't put them in the washing machine with an agitator. (Front loaders do just fine.) It is plastic, so really all it needs is some dish soap or liquid laundry soap, a quick rinse, and hang dry. I don't recommend these for running if your thighs will rub together (my hubby's ripped from the friction). But for the price, these are worth it!
I bought this sauna suit for my husband for Father's Day, he wore several times and was very satisfied with it because it really made him sweat during and after his workouts. However, because he wore it so often, for the sake of hygiene, I dropped the suit in the washer to get the sweat off... and the pants came out ripped from one end to the other.I got a replacement, but now we rinse it by hand in order to avoid tearing it (not very convenient...)
