The
  Proframe RS Helmet takes the lightweight breathability of the Proframe 
 and takes it to the next level of safety and performance. Featuring the 
 all-new MIPS™ Integra protection system, which combines an EPP liner 
 with an EPS layer and is designed to reduce rotational forces in a crash
  otherwise transmitted to the brain.

Designed to meet the 
 needs of all-mountain riders and enduro racers, the increased 
 ventilation and decreased surface contact of the helmet keep you cool on
  long rides, while the Ionic and anti-microbial liner and cheeks pads 
 provide optimized comfort and fit. Fit is also assured care of the BOA® 
 fit system, offering class-leading fit and security, and the Fidlock® 
 magnetic closure system for easy-open and close use, even with gloves.

The
  3-position adjustable visor is compatible with goggles, and those 
 looking to capture every sweet run will appreciate the removable, 
 under-visor GoPro mount on the Fox Proframe RS mountain bike helmet.
