JIN Carbon Design Helmet

JIN Helmets are constructed with a fiberglass and kevlar shell. The helmet passes international safety certification tests with up to a 30% safety margin. The shell exterior is smooth, increasing the slide effect in the case of a fall, and chin straps are affixed low at the base of the neck to increase helmet stability. The interior padding is fabric, and can be removed for washing. One interior pad is included with purchase of helmet shell. Additional interior pads must be purchased separately.
