The Smith Youth Upstart Junior Snowsports Helmet is a modernized version of the traditional full-shell junior helmet. Clean, cool, and hip enough to make the older groms jealous for a change. Featuring Bombshell Construction with Full Ear Coverage and AirEvac ventilation to reduce fogging and control temperatures. Bombshell Construction-Injection molded ABS shells withstand high-impacts and offer unparalleled durability. For when you need your helmet to be as tough as your truck, Bombshell delivers. Smith AirEvac chimney vents and under-shell vent channels actively pull hot air out of user's goggles to prevent fogging and increase ventilation.
