The Black Knight Ion Storm XT squash racket double pack is comprised of two head-light, balanced rackets brimming with technology that creates a stable racket with a large sweet spot for consistent hitting. Aerodynamic properties are enhanced by the Thin-K technology in the frame & the Power Nick 19 strings, which also give extra hitting power. The Power Surge system reduces the effect of vibrations & stiffens up the feel of the racket. Durability & structural strength have been enhanced by the 16K hyper tensile fibre & Nano-Crystalline technology. The rackets are supplied with full length protective covers.
