Find out why SmartPaker Al decided to give the GPA Speed Air 4S helmet from the Redline Collection a try—and what her favorite feature is! Shop Now: https://www.smartpakequine.com/rider-apparel-and-gear-365pc Why We Love This: The GPA Speed Air 4S helmet, part of the Redline Collection, is packed with advanced safety technology backed by 50 years of expertise. Unlike traditional helmets that have two layers, this helmet features four layers designed to maximize shock absorption and double your protection. The 4S Breakdown: 1S: Outer shell made from absorbed polymer that deforms on impact to absorb the initial shock. 2S: Interface layer that further absorbs impact energy to reduce force. 3S: Reinforced fiberglass main shell that provides rigidity and protection after shock absorption. 4S: EPS foam liner that finishes decelerating the shock to protect the skull and minimize cranial injury risk. Favorite Features -Turbo-effect visor channels airflow through air vents while reducing lift at high speeds, lowering fracture risk. -Speed Air Ventilation with three front and two rear louvers for superior airflow between the helmet’s two shells. -Leather chin strap and anatomically designed black stitched leather jugular with four riveted fixing points for a secure fit. -Red leather interior EPS contour for added comfort, durability, and style. -Interchangeable and adjustable foam padding with antibacterial, breathable, and Coolmax treatment for a perfect fit. -Machine washable interior for easy care.
