  • VaporFit™ fit system uses a tried-and-true rotary dial adjustment system integrated with a tuned elastic fit using engineered shapes to fit every rider with 1 of 4 shell sizes
  • VaporFit has 5cm of rotary adjustability and can be moved up/down or forward/backward at the attachment points, providing a personalized, secure and comfortable fit
