Nike Mercurial Lite Manchester United The Man United Mercurial Lite is the result of an elite partnership - Red Devil aesthetics combined with Mercurial performance. Anytime Nike brands something Mercurial, you immediately know it's fast and lightweight. These shin guards are no exception, featuring 72% polyurethane and 28% EVA construction. The Mercurial Lite's low-profile provides protection while not distracting the athlete. The durable shell is bonded to a dense foam backing for excellent impact diffusion and comfort against the skin. The guard lock sleeve with directional stretch material provides enhanced security and increased comfort, while the anatomical left and right design is engineered and tested to fit the contour of the leg. The NOCSAE approved Nike Manchester United Mercurial Lite will offer all the protection you need whether your pitch is just around the corner.
