Source MIPS Helmet

Trail riding just got a new ally with the Giro Source MIPS Helmet. The Source finds all the vent holes you need to stay comfortable under the summer sun and on sweltering climbs, and even resources an adjustable visor to help block out sun flares in the woods that can make visibility tricky. Giro makes fitting a cinch with its Roc Loc 5 system and Coolfit padding. To up the safety and reduce the weight of construction, Giro uses an InMold process which bonds the outer hard-shell to the foam liner. And MIPS’ safety system sits just below for added protection.

  • Mountain bike helmet with MIPS technology and a durable shell
  • Cooling vents with internal channels help with cooling under intense sun
  • Adjustable visor blocks what your sunglasses can't
  • Easily adjusted fit system with a roll-dial on the back
