The Giro Fixture has always been a crowd-pleaser and this updated version, The Fixture MIPS II, is even better. It has the same Loc® Sport universal fit system, so you don't need to worry about finding the right size. So long as your head is between 54 and 61cm in circumference then it will fit. The MIPS slip liner is still present but it has been re-integrated for greater effectiveness at dissipating torsional forces on the head. The ventilation has been redesigned too. Now with 16 vent holes for cooling comfort, even on the sweatiest of fire-road climbs. At this price, the Fixture MIPS II can't be beaten for fit, price and protection.
