Remember to measure for the perfect fit. The newly redesigned Troxel Spirit Riding Helmet is better than ever. The Spirit now offers a deeper, full-coverage fit for increased security. The sleek new low-profile design and DialFit technology work together to create a personalized, comfortable fit for a variety of head shapes. Finally, the strategically-placed mesh-covered vents increase air flow to keep you cool on long rides, while the shatterproof FlexVisor helps shield your eyes from the bright sun.
