The Hard Charging All-Rounder

The Sentinel inspires confidence like you're wearing full body armor.It's forgiving do-it-all attitude truly blurs the lines between planted bottomless sender and playful poppy trail pony. Whether you're chasing EWS dreams or just a weekend afternoon escape, it will bring out the best in you. So easy to get acquainted with you'll find yourself sending lines, jumps and maneuvers you always felt were beyond your ability. Where before you went around, now you go over. Where you pushed up, now you pedal. Where you rolled, now you boost.
