New in 2011 this pad has been redesigned to increase the comfort by adding ventilation ports. This increase in air flow helps keep a players head cooler. This pad replaces the original part Surefit Air Liner part number 78940141017. This liner also fits the Youth Air XP

 
The two-piece air liner is the secret behind the fit and comfort of our helmets. With two inflation ports, the SUREFIT™ Air Liner gives you a precise custom fit and is made from a soft, but durable anti-microbial material.

Valve Attachment System
This new hook and loop attachment system locks the inflation valves into place. There’s no more struggling to keep the valve aligned to the helmet shell.
