The Persist was created for cyclist that look for a stylish helmet with a tailor-made fit. The adjustable VaporFit system provides a customized fit, while the MIPS liner adds an increased level of protection. The Persist features 21 optimally placed vents that work with internal air channels to keep you cool and comfortable. The AirEvac system efficiently pulls hot air off of your eyewear to prevent fogging. Pass-through channels allow eyewear to be easily stored on the front of the helmet.
