The Morrison MTB Helmet is Bern's first mountain bike release featuring the same Zip Mold as Bern's popular Allston helmet. Tough, PVC shell is fused with Zip Mold liquid-injected, PU hard foam for a higher strength to weight ratio than EPS helmets. The Morrison is updated with extended coverage in back for more impact protection, a new liner for better moisture management and a Twist Lock Fasten System for fine-tuning the fit. Large channeled vents offer 2x more airflow than Bern's other leading helmets and the detachable visor protects your vision. Sink Fit design surrounds your head for a great feel, plus it accommodates sunglasses or goggles. It's also compatible with Winter and Audio liners, making it perfect for year-round use.
