Your mini-me is as unpredictable as a loose cannon on the best days, which is why it's absolutely critical that you get their noggin covered before saddling up on their steed for a ride. The Giro Tremor Helmet comes loaded with a strong polycarbonate shell, and EPS foam for absorbing impact. It is designed to fit for a few seasons, with RockLoc adjustable fit that cinches down to stay steady and secure, and soft, moisture-wicking pads that add comfort to the fit, while pulling away sweat on the hot days. When the temps start rising you'll find that the 18 vents covering the helmet keep cool air moving in, and warm air moving out the back to keep your little one comfortable throughout the warm seasons.
