Saris Sweat Guard Black, One Size

Previously known as the bike thong, the Saris Sweat Catcher does exactly what it describes while we're on the trainer. Though it may resemble women's undergarments, when it's on the bike it prevents corrosion and sweat from getting where it shouldn't. We tie this nifty device up between our saddle and stem while we're on the trainer to catch all our corrosive sweaty offerings.
