Fox Racing Flight Sport HelmetFor relaxed park sessions on two of four wheels, leave the 100g glorified roadie helmet you use for XC endurance and 'cross events at home. After all, you're in a dirty, drained pool; not on a time trial course. Fox Racing's Flight Sport Helmet is a classic, understated lid that doesn't make any unsupportable claims about your skill level and ambition. Instead, its basic EPS foam and ABS shell let your mad skills and loud socks do the talking.
