Protect your cranium in a crown of comfort with the R.E.D. Tantrum Helmet. A step down from the full-featured R.E.D. Frequency Helmet as it does not include the dual component, custom conforming liner, the Tantrum is actually a bit lighter and still offers plenty of comfort and performance features. Molded into the polycarbonate shell multiple vents provide a steady stream of fresh air to keep your head from overheating. When cold, stormy weather arrives, simply push the exterior Climacontrol tab to partially cover or completely cover the overhead vents. Also, six independent vents, three on each side, offer even more air circulation. Accessory vent plugs come with the helmet to seal these mesh covered openings as needed. To dial in the fit, the MC Squared, Mechanical Fit and Comfort System, adjusts the liner's circumference to match your head's, in a manner similar to popular bicycle helmet models. Likewise, a Zip Clip ratcheting chin buckle offers fine-tuning without removing the R.E.D. Tantrum Helmet. For music lovers, the warm Quick Clip ear pads pull-out for easy replacement with the Audex Audio Ear Pad Accessory, turning your helmet into a portable sound machine that's iPod MP3, and CD player compatible.
