Giro Tyrant Spherical MTB Helmet - Matt Metallic Black-Ano Lime

• MIPS Spherical Technology: Utilizes a pair of foam layers that work like a ball and socket to redirect impact energy in a crash. One layer is EPS, which is well suited to high-speed crashes. The other is a lower density EPP foam with rebound characteristics to address low-speed, roll-around-in-the-dirt-type spills.
• Tool Free, Bolt On, Adjustable Visor
• Channeled Stack Ventilation: Vents at the brow line help warm air to be drawn up and away from goggles/glasses and draw air through the helmet for maximum breathability
• Check Pads: Includes two pair of pads for fit tuning
• Quick Dry Padding
• Hardshell with In-mold polycarbonate Hardbody lower wrap
• Progressive layering with EPS outer liner and EPP inner liner
