The Sparco RW-4 balaclava is a single-opening racing hood made from soft interlock fabric. It is a straightforward under-helmet layer within the RW-4 range, rather than a bundle of underwear pieces.

Try it beneath the helmet you intend to use. A comfortable hood should sit smoothly without bunching around the forehead or altering the helmet’s fit; sizes advertised for RW-4 shirts and socks do not describe this one-size hood.
