The Mantis Power 130 II double pack is comprised of two of these evenly balanced intermediate & advanced level squash rackets. With a large head size the sweet spot is bigger & more forgiving when hits are not in the centre of the racket, & the fan-shaped string bed also increases power potential. The rackets are 100% high modulus carbon constructed which makes the frame strong, & the strings are Mantis T-Power White, strung in a 14x 18 pattern. The rackets are supplied with full covers which have a carry strap.
