ALPINESTARS ZX LS PREMIUM UNDERSHIRT (2016 Design)
Through the use of a new proprietary fire retardant fabric exclusive to Alpinestars, the ZX Series of racing underwear proves to be more breathable and comfortable than Nomex. Through a revolutionary tubular knit construction, the Alpinestars ZX Racing Undershirt is nearly seamless and offers a comfortable, form-fitting fit. The naturally breathable Lenzing FR fabric is excellent at wicking moisture from the skin while being hypo-allergenic and anti-microbial. Softer than Fire-Retardant Cottons and Nomex materials, the ZX series will make you want to wear fire resistant underwear again!
