The Sentinel is TSGs latest full-face helmet, built for next level aggressive mountain biking and BMX racing.The helmet is created in collaboration with one of the industrys most legendary helmet designers and the super-tough ABS outershell makes it possible to build a sleeker more solid silhouette with the added strength of a toughened PC-laminated EPS foam protective face guard. 12 vents maximize airflow through the helmet at all speeds and a wide eyeport with precision placed visor deliver superior vision and will accommodate a wide range of premium goggles. To top it off, the Sentinels comfort liner and cheek pads are removable and washable, so however hard the helmet is ridden it can be kept as fresh as when it came out the box. Just add a bike, bravado and beasty mountain and its time to rip.
